Are you using transparency? I find that antialiasing and transparency 
just don't work well together; the antialiasing gets turned transparent, 
which makes it look awful. I'd love to hear advice on this topic, as I 
have similar issues with fonts and symbols looking crummy under 
transparency.

If it's not transparency, how about your image format? Are you using 
JPEG? JPEG is nice stuff, but you've probably seen JPEGs that get all 
crummy if someone tried to compress too hard. Try setting the 
OUTPUTFORMAT options to turn up the JPEG quality to 100.

Anything beyond that, we'd probably need to know a thing or two about 
your image format, maybe see an example of it, ...
