Template:Userpage formatting[edit]

I'm trying to add formatting parameters to Template:Userpage (e.g. for changing the background color), but having some issues. I introduced them to Template:Userpage/layout, but I gather that I need to pass them through language variants like Template:Userpage/en to get them to be usable. But when I try to add something like 

|border={{{border|}}}
|background={{{background|}}}
|extra-style={{{extra-style|}}}
|file={{{file|}}}

to the English translation, it shows in previews that undefined values are interpreted as blanks rather than just ignored. How do I get around this? Best, {{u|Sdkb}} talk 19:48, 5 December 2023 (UTC)Reply[reply]

Internal error: The server could not save the temporary file[edit]

Hi!

When I upload some larger files, I get the following error: "Interner Fehler: Der Server konnte keine temporäre Datei speichern." (Internal error: The server could not save the temporary file). Is someone encountering the same? I saw this error yesterday already. --PantheraLeo1359531 😺 (talk) 16:03, 7 December 2023 (UTC)Reply[reply]

Making content in template only visible to a certain user group？[edit]

is there a way to make certain things only visible to say registered users or autopatrollers?

a use case would be transcluding certain maintenance related stuff (so only useful for commons users but not any website visitor) on category pages. RZuo (talk) 13:46, 10 December 2023 (UTC)Reply[reply]

It’s technically possible using the classes defined on the CSS pages listed at Special:PrefixIndex/MediaWiki:Group-, but I’d recommend against it except for things that are totally useless for users not in the given group (e.g. hiding delete buttons for non-admins is okay, since they can’t delete pages anyway), as logged-in status or user groups are not good proxies for what the user’s intentions are – maybe an experienced user didn’t log in because they decided not to create an account, use an insecure computer, don’t want to go through the 2FA login process etc.; and conversely, maybe a logged-in user isn’t really a contributor (and as such doesn’t need the maintenance links), but someone who only came here to upload a few pictures or even someone who never wanted a Commons account, but got one due to central login. —Tacsipacsi (talk) 17:31, 10 December 2023 (UTC)Reply[reply]

Path between categories[edit]

Upload wizard change[edit]

The upload wizard design seems to have been changed in the last day or two. Is there any possibility that whoever changed it could provide more space for answers to 2. Where did you find this work? Enter the website, the book, or another source. and 3. Enter the name of the original author of this work., both of which questions often require more than a single short sentence. By way of example, for an image I've just uploaded I'd like to give the following information for q.2 - which used to fit in the edit box before this change; now there's a single line edit box which requires both horizontal and vertical scrolling to try to make any sense of the input text:

Upper Wharfedale : being a complete account of the history, antiquities and scenery of the picturesque valley of the Wharfe, from Otley to Langstrothdale via Internet Archive - https://archive.org/details/upperwharfedaleb00speiuoft/page/n177/mode/2up

When should an image where uploader stated "own work" get a "no source" speedy deletion nomination?[edit]

When should an image where the uploader stated the image was their "own work" trigger a {{No source since}} speedy deletion nomination?

I upload some images I took as {{Own}}. I don't ever remember my {{Own}} images getting challenged. Should an assertion of "own work" be challenged just because the uploader is a relative newbie?

Yes, if the challenger thinks they have reason to believe the uploader is a sockpuppet, or otherwise not credible, there should be a way to challenge the image's provenance. But is a bald {{No source since}} tag the right kind of challenge?

User:Kacamata has recently applied many {{No source since}} tags, including [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38].

Near as I can tell Kacamata didn't really offer an explanation as to why he or she doubts whether these own work assertions are credible. Should he or she have offered an explanation? Geo Swan (talk) 05:39, 15 December 2023 (UTC)Reply[reply]

Hi, IMO "no source" shouldn't be used if a source like {{Own}} is stated, even if this source is suspected to be wrong. "No permission" is better, or speedy deletion if there is evidence of copyright violation, or a regular DR. Only for an old document probably in the public domain claimed as own work, a "no source" might be useful: we don't need a permission in this case. Yann (talk) 14:12, 15 December 2023 (UTC)Reply[reply]
Normally, I tag as no source all the files that are clearly not own work and have no proper source. Most of the time these are copyvio. Files that are clearly taken from elsewhere. When I can locate the image source on the internet, I tag them as copyvio indicating the source. Almost every time I tagged a file as no source, it was deleted by a sysop. Normally, the files I tag were uploaded by accounts from pt.WP. It's very common for socks, vandals and spammers to create articles in the pt.WP, and then upload problematic images here on Commons. Again, these uploaders are not reliable and almost always their claims of "own work" are not credible. By the way, all this conflict started because Geo Swan is trying to keep out of scope unused images uploaded by a LTA and spammer who created dozens of socks and have being trying to spam pt.WP for a long time. To me, it's shocking that a user goes to this distance to try to keep images uploaded by unreliable accounts (socks, trolls, spammer, etc.) with clearly not credible assertion of "own work". Kacamata! Dimmi!!! 15:51, 15 December 2023 (UTC)Reply[reply]
Sure, I support deletion of such files, but "no source" is the wrong template. Yann (talk) 16:15, 15 December 2023 (UTC)Reply[reply]
  • User:Kacamata, you wrote "I tag as no source all the files that are clearly not own work and have no proper source. Most of the time these are copyvio..." I linked to close to three dozen images you recently tagged this way.
Frankly, A LOT OF THEM seemed to have very credible claims that they were the own work of uploaders.
  • Could you please explain, more fully, how you reached your bogus conclusion on these "own work" claims?
File:Estátua_de_José_Lopes.jpg looks old, but it bears the date 1958, so the sculptors copyright matters, and it merits a challenge. However, the related File:Igreja paroquial de Lamelas.jpg mainly shows the old church, and I suggest the sculptor's copyright claim on the 1958 monument, should be dismissed as "de minimis". I don't believe either of these images merits tagging for speedy deletion due to "no source".
  • Some of the other images you tagged as "no source", like File:Mariuva 2.png, could be deleted, but for other reasons than "no source". In other recent discussions you have argued for deleting selfies, as "self-promotion", even when the uploader is someone with a credible claim of notability. User:Mariuvavalentin, who recently uploaded three images that look like selfies, doesn't seem to have a credible claim of notability. So, I agree, her selfies merit a challenge over whether they are in scope. I think it was a mistake for you to nominate any of those three images as "no source", when they are almost certainly selfies.
  • There are some other images among those three dozen that do merit a challenge, but I strongly agree with Yann's suggestion that when your real concern is that the image looks like a copyright violation, you really should offer that as your deletion justification. WMF projects require experienced good faith contributors to do their best to educate inexperienced good faith contributors. In your case, if you are going to continue to nominate images for speedy deletion, I suggest it is essential you apply the best speedy deletion tag, so those good faith new contributor can learn from their mistakes.
  • Frankly, your revision history shows you have a long history of leaving heads-up on newbie's user talk pages, informing them their images were tagged for speedy deletion due to lacking a valid source. A good faith newbie won't know, can't know, when they are authorized to upload images they took themselves, accompanied with a tag that the image was their own work.
Frankly, if I am correct that you routinely tagged images with credible claims of "own work" as "no source", then I am concerned that your record suggests you triggered the deletion of a very large number of perfectly valid in scope images. Geo Swan (talk) 14:42, 16 December 2023 (UTC)Reply[reply]
I deleted Mariuvavalentin's files, as pt:Mariuva valentin was deleted, this person doesn't seem notable, and this user has no contribution outside self-promotion. Yann (talk) 14:53, 16 December 2023 (UTC)Reply[reply]
Update
Just to be clear, User:Yann recently wrote "Where this is the slightest possibility that the file is OK for Commons (for whatever reason), a proper DR should be created." I totally agree. And I think that this means that, so long as a contributor is in good standing, their "own work" images should not be tagged for any kind of speedy deletion, including both {{No source}} and {{No permission since}}.
If a newbie has made a couple of mistakes, and DRs show they have a history of applying "own work" to images innappropriately, would speedy deletion requests then be appropriate - if they linked to the DRs that establish earlier errors? Geo Swan (talk) 17:03, 18 December 2023 (UTC)Reply[reply]
In the 3 cases mentioned above, "no permission" is appropriate. EXIF data shows a different name than the uploader, although the images are in high resolution with full EXIF data, so we can assume the images were not copied from the Internet. Yann (talk) 17:17, 18 December 2023 (UTC)Reply[reply]
Thanks for the prompt reply. Geo Swan (talk) 18:26, 18 December 2023 (UTC)Reply[reply]
@Yann I believe this went too far. Geo Swan is known for being stalking, harassing and wikihunting people. They were banned from en.Wp for this same reason. They are now pinging in several places in a clear attempt to harass me. I believe this kind of behavior should not be tolerated here or in any other WMF project. Kacamata! Dimmi!!! 21:39, 18 December 2023 (UTC)Reply[reply]
Funny thing is that @Yann said that the tagging was "is appropriate". And yet, Geo Swan reverted my tagging in File:AmandaLeadroDuo.jpg and File:Amanda Maria Fest Sorocaba 2023 2.jpg and started a DR. This is a clear example that they are not acting in good faith. They are just trying to harass me. Kacamata! Dimmi!!! 21:59, 18 December 2023 (UTC)Reply[reply]

How to edit the location of creation in the structured data of an image[edit]

No, this photo is not taken from Reading Abbey

I'm used to being able to edit the 'location of creation' in an image's structured data by using the edit button, but that button seems to have disappeared for a number of properties, including 'location of creation'. Not sure why this is, but it is quite important to be able to do it in order to modify or remove locations set by the GeographBot, which in my experience quite often either gets it completely wrong, or uses a location that is too general to ever be of any use.

As an example of what I'm talking about, the picture here of Reading station has a location of creation of Reading Abbey!. The ruins of Reading Abbey are actually about 500m in front of the camera, and a little bit to the left, beyond the big pink office block. And I seem to have no way of correcting this.

I originally asked this question at Commons:Help_desk#How_to_edit_the_location_of_creation_in_the_structured_data_of_an_image, and despite a few suggestions there, the problem persists. I suspect that it is also related to the issues raised by another editor at Commons:Help_desk#Can't_add_structured_data_statement. One suggestion was that I raise it here, so here goes. -- Chris j wood (talk) 11:12, 22 December 2023 (UTC)Reply[reply]

@Juandev: Disclaimer: I'm old. But IP range blocks don't generate any content in the user log at all AFAIK. We're generally fairly cautious with connecting IP addresses with registered accounts for privacy reasons. If a user is say...in a place like Turkey or China where they may need to use a proxy to contribute, they would need to request a special permission in order to avoid the IP block.

Colors not showing up correctly on SVGs?[edit]

File in question

Hello!

I recently fulfilled a request at the Illustration Graphics Lab for a logo, but I noticed something weird when I uploaded it...

The colors are wrong! Especially the blue! It was supposed to be #0000FF, but my eyedropper tool says that the PNG rendering has #5401FF as its color, which is closer to purple! Why is that? QuickQuokka [⁠talk • contribs] 20:39, 24 December 2023 (UTC)Reply[reply]

So, I just checked it out on my phone, and it looks like it's alright at the expected color, so I think this problem may be on my end, but why though? QuickQuokka [⁠talk • contribs] 20:58, 24 December 2023 (UTC)Reply[reply]
I do not know, but here are some issues.
The SVG colorspace is sRGB.
When WMF's rasterizer converts the SVG to PNG, it does not specify the sRGB colorspace.
When the PNG is painted to the screen, there may be a colorspace conversion.
When the color picker selects a pixel, it may read the device colorspace.

SHA1 hashes[edit]

There are SHA1 hashes available in PetScan for each file from Wikimedia Commons. I suspect this is information received via API from Commons.
