What Links Here Bug

Below demonstrates that pages that link via :Image:Filename aren't shown in the File links section of the corresponding files page.

This is a pretty serious bug, as people may delete such files, believing that they aren't used.

That is, correct would be the page "Image Bug" being shown in the "File links" section of both jpg's. It is however shown only in the "File links" section of the second jpg.

GIF Bug

Test page showing the GIF bug in cpcwiki. If it is a bug... or is it a subtle anti-compuserve campaign...?

Below GIF and PNG are pixel-identical images, but, the GIF is shown correctly only in fullsize, but not when resampled to smaller sizes.

100px

Error creating thumbnail: Unable to save thumbnail to destination
  • PNG 100px - okay


Error creating thumbnail: Unable to save thumbnail to destination


Fullsize

Error creating thumbnail: Unable to save thumbnail to destination
  • PNG full


Error creating thumbnail: Unable to save thumbnail to destination
  • GIF full


wikipedia

Another example of the GIF problem. Observe that wikipedia DOES show the same imapge properly (see http://en.wikipedia.org/wiki/Columbia_River_Knife_%26_Tool).

Sorry about the martial looking example, it was the first file found on wikipedia when searching for "gif schematic" being shown in a gallery.

history

The gif image bug dates back (at least) to 2007, unwanted transparency was reported here http://cpcwiki.eu/forum/index.php/topic,72.msg461.html#msg461 will that ever be fixed?
