--- Comment #1 from Vincent Povirk madewokherd@gmail.com 2011-10-13 16:11:43 CDT --- Try adding ImageFlagsEncoder to the entries in the codecs array (http://source.winehq.org/source/dlls/gdiplus/image.c#L3251). That won't fix the problem, but it might help figure out which encoder the program expects.
