Or, even better, switch to .png graphics. Unlike JPEGs, which will lose
information every time you open and save them, .png graphics, which IDL
supports in 5.4 (I don't know when they started support...) are like
GIFs, but without the copyright issues that forced RSI/Kodak to remove
gif support from IDL 5.4. And as for publishing them on the web, they
aren't as wide-spread as JPEG files, but the major browsers version 3.0
and over support them, which is >95% of your audience (and yes, I know
that some out there will say "what about that <5%, they deserve to be
recognized", but at some point, you have to go to the better standard
and hope people catch up).

Another interesting idea that I use is to write some scripts that will
use ghostscript to automatically convert a .ps file into, say, a PDF
which you can post on the web. This way you can still get vectorized
graphics (for simple plots), and you can produce it "directly" from IDL.
