1) Get a copy of a recent version of GIMP. It is _wonderful_.
http://www.gimp.org
2) Sufficient memory in your machine. For image manipulation, at least 64 Megs
is needed.
Make the screenshot.
Save it as a non-indexed file. The gimp's own format .xcf or .xcf.bz2 is fine.
Work on the picture, and then convert it to .ps or .eps _with sufficient
resolution_
Import it into the document.

If you use the html2ps program to generate the PostScript you will be very
surprised by the printed results.

It's not _that_ bad.
Make sure that:-
1) you do all the image work on non-indexed images ( very importand )
GIFs are usually indexed, convert them to non-indexed before doing _anything_
2) You _never_ save as .jpeg, the jpeg compression ruins the print quality
detail in the picture.

The online GIMP manual is at:-
ftp://manual.gimp.org/pub/manual/
There is a very good Latex introduction; go to:
