Sorry I've overlooked this. Crashing one's browser is a real problem and I 
will look to your patch.

The best solution to second problem would be an JPEG2000 format. This is in 
most cases not applicable, so only possibilities are:
a) GIF->PNG conversion only (may crash browser)
b) background color guessing (need to parse a HTML-> overkill) 
c) nothing to do (but there are some huge GIFs, which may choke your 
connection...) 

Seems I will add an option to let people choose between normal, a) and c) 
behaviors. Any idea what another possible option is there?
