Re: Shrinking a lot of jpegs?

[Michael Slack <mslack@xxxxxxxxxxxxx>]

Yes, ImageMagick is great.  If you like Perl there is also PerlMagick, which 
is really just a Perl module binding to ImageMagick.  Great for custom 
scripting image manipulation, like "on the fly" image drawing/manipulating for 
web pages, etc.  O'Reilly's Programming Web Graphics with Perl & GNU Software 
has a whole chapter introduction to this module.
