Hi Karl,

what's your motivation for this commit? I think transparent gifs should be displayed transparently in Squeak. You can always add an opaque background in your application if it does not want this :-)

Apart from that: Why don't you use #detect:ifFound: here? There is no need to scan all images after one that contains transparency has been found. I guess.

I was afraid this would be a slow search, but its negligible.
Tested performance on a quite big gif* and it was only 1900 ms on my slow computer
