Forum:Used, but technically unused images

Recently, I've been going through and deleting the unused images on a wiki I adopted. But some of them are actually used, like the wordmark, background, and favicon. What are all of the "unused" files that I shouldn't delete, for both Monobook and Oasis? SereneChaos 19:05, September 10, 2011 (UTC)


 * Wiki-background
 * Favicon
 * Wiki-wordmark
 * Custom achievement images
 * All the images used via MediaWiki:Wikia.css, MediaWiki:Wikia.js, MediaWiki:Common.css, MediaWiki:Common.js, MediaWiki:Monobook.css and MediaWiki:Monobook.js
 * That's the ones I'm aware of. — Sovq 19:08, September 10, 2011 (UTC)


 * Are there any for fourms? Also, is this image needed? SereneChaos 19:10, September 10, 2011 (UTC)


 * File:Forum new.gif is used in forums and File:Wiki.png is used in monobook.--Sxerks 19:16, September 10, 2011 (UTC)


 * Okay, thanks! SereneChaos 19:20, September 10, 2011 (UTC)


 * Just to throw in my two cents worth — and in this case, it really is worth about two pennies — the presence of a file on the Special:UnusedFiles list is not a good enough reason in itself to delete an image. It's kinda impossible for anyone outside your wiki — and difficult even for your members — to know which images are truly unused.  Anything linked through CSS or JS will not report links, and therefore will end up on that list.  Not only are there the standard things you've listed above, but there are tons of images which could potentially be customised.


 * You'll want to go through all your CSS files and all your JS pages and see if there are any specific references to images in there.


 * Then, you might want to consider having a bot place unused images in a category, so that you can more easily sift through them and figure out which ones you want to keep for potential use later on down the road. There are all sorts of reasons why an image might be unused at any given time, only some of which having to do with an actual problem with a photo that might trigger its deletion.


 * But destroying images simply on the basis of whether they're being used at the moment might be a case cutting off your nose to spite your face.  Especially if you're taking over a wiki and don't yet know what's hidden in all its nooks and crannies.  19:27:30 Sat 10 Sep 2011


 * Well, images have been unused for years in some cases. I haven't deleted many, just the ones that I've found what they were used for. There's many I have no idea what they were uploaded for, so I've been very hesitant to delete them. SereneChaos 19:35, September 10, 2011 (UTC)


 * These images will probably show up in Special:UncategorizedFiles as well, I usually add them to a category like: Category:Site Images.--Sxerks 02:24, September 11, 2011 (UTC)
