If I import them, they are still corrupted - for example, I'm working with gif 
images that have  no transparencies, but certain pixel values are transparent  
once I try to use them from ImageImports (displaying them on web page via 
Seaside code). If I open vs. Import it looks ok. Also, Imported images with 
text in them will have the edges of the text become noisy, but opening them 
one at a time looks fine within the image. Looking at them in a browser 
before importing them shows them to be correct.

It's as if certain pixel values are translated incorrectly, but I'm not too 
good at manuipulating an image yet from within Squeak.
