So, another thread in support of a new tag on Demozoo - I've established <a href="http://demozoo.org/productions/tagged/cannot-decode-image/">cannot-decode-image</a> for cases where an image is either not supported by any known decoder so that we can have a screenshot, or it is supported but plain does not work. I'll try to provide details in the comment of each entry :)
Plz to be help.
