As a *general* rule of thumb - and not to be taken as always true - is that;

o For complex images when there are few easily definable edges (photos, art 
work, etc.) JPEG works better.

o For vector images when the edges are definable (images of text, line art, 
etc.) GIF or PNG works better.

PNG has the better facility of having layers, so that you can anti-alias the 
text layer, but leave the graphics layer untouched.
