Forum:Deleting Talk Pages Only Images

So I was doing some conversion of JPGs to PNGs, and discovered that a majority of them are only used in talk pages that have long since been resolved. And checking these Images Used only at Talk Pages, I see that they are all resolved and are just a burden to this wiki if we keep them here. Reasons include:
 * 1) Problems have been resolve, pointless to keep them any longer.
 * 2) Some are very poorly named, renaming them would be forcing open some closed forums and  archived talk pages.
 * 3) A good deal of them are JPGs, no sense in converting them just for a long ended talk.
 * 4) Some of them are poor quality.
 * 5) Some are doctored/marked, with highlights, boxing, collages, etc, which are all not allowed in our image guidelines.
 * 6) A few of them are actually scanlations.
 * 7) Some have no sources, and probably would take a long time to find those sources.
 * 8) Some may be duplicates of images that we are using for articles (like we already have this, and we don't need this).
 * 9) Some are just charts, screens, and whatnot created by users, not taken from manga/anime/other related sources.

My suggestion is to erase all these long-due images (if we cannot find a single good use for them in any articles/templates), replacing them with a Redlink. And in the future, any talk page only images should be deleted once the talk has been resolved. 04:18, August 2, 2015 (UTC)

I'd kind of support keeping them just for archiving purposes, and maybe in case a user might want to talk about something that's already been resolved. But I have no problem with them being deleted anyways. They've served their purpose. 04:33, August 2, 2015 (UTC)

A lot of them have already been deleted anyway like ones on user talk pages. So it can go either way. The ones I will absolutely support getting deleted are ones that were incredibly pointlessly uploaded when they could have just been externally linked. SeaTerror (talk) 18:58, August 2, 2015 (UTC)

Well, first off, all those useless ones would be the charts and graphs and other wiki background screens. Technically, if they are used only for talk pages, then ALL images can be externally linked. 01:13, August 3, 2015 (UTC)

I also checked, though not related to this topic, that there are other JPGs that are not yet marked with the Jpg. Is there anyone who knows how to track down all files of one type? 04:07, August 3, 2015 (UTC)
