High quality images

[T.W. Smith]

Hi,

CAVEAT: Dov does not like this content, and I respect his judgement.
Nonetheless, I believe there's good information here on the whole. two
points:

1) Take a look at Screen Captures 102 here:
http://www.techwr-l.com/techwhirl/magazine/technical/screencapgraphicshomepage.html
.

2) Drawing software tells me you're using vectors and want to use EPS
instead of rasters like PNG, GIF, TIFF, etc.

Cheers,

Sean
