Can confirm on Linux that the "save image changes to epub" action is somehow destroying the gif in Sigil's scratch area. I haven't determined if the crop attempt is required to trigger it or not. But there's no need to do a Save/Save As of the epub. Examining the scratch area after the "save image changes" is enough to reveal the zero byte file. Just closing the epub does not write the changes (or prompt that changes have been made). This is with Sigil 2.8.1.

It's a pretty neat trick for a QtImageIO plugin that claims to be read-only.
