Description

This could also be "just" a feature request. I did not find a hint on http://doc.tiki.org/Tiki18Question whether TIFF is supposed to work in file galleries or not.

In fact, TIFF doesn't work. You can upload it, and it will be correctly classified as image/tiff, but it will not get a thumbnail and will not show if included on wiki pages. But astonishingly EXIF information is (to some extent) correctly extracted from it.

I could reproduce this bug (or lack of feature) on Tiki show2, on an instance I created for another bug report:
http://hman-11504-7252.show2.tikiwiki.org/tiki-upload_file.php?galleryId=1&fileId=1Question

This could be an issue of GD which uses plugins for GIF and JPG, but I did not see a plugin for TIFF. Both on my ISPs PHP installation and that of Tiki show2, only JPG and GIF are listed on phpinfo about GD.

If it is a GD issue, IMHO Tiki should show a warning that TIFF support depends on a library not found locally. Since TIFF is the de facto standard for scanner output, it would be a pity if TIFF support could not be achievable (possibly - but did not reseach on that - because of patent issues?).

Thanks
