This is a question regarding graphics in your documentation:

I notice that these pictures generally have only a few colours, (except 
for the title bar which is shaded).

For pictures like these, it's better to use a compression that works 
well with few colours.

What I mean is, I think jpeg works on the shades within a picture, and 
smothers them, but our eyes can't really tell the difference.  The think 
is, with low numbers of colours, and sharp edges, (as in the text in the 
dialog boxes) our eyes can.

I am writing this message to ask about what formats are best for what...

A lot of people may assume jpeg because of the high compression ratio, 
but I'm not sure this is the right answer...

Could it be possible to generate some documentation on what format is 
best for what...

I've seem to have in my ming that pcx and gif are good for low colours, 
eps is good for vector graphics, and some graphics (I don't know much) 
and jpeg for photographs.

There may be others that are better for renderings (as these typically 
contains different types of shades than photos)

Any info would be a great resource!!!
