exec with convert is very powerful, but can have performance issues,
as firing up exec with a mini-shell can get kind of expensive.

Here is a thumbnail script I use:
http://uncommonground.com/thumbnail.phps

Here's the pathinfo.inc file referenced within that:
http://uncommonground.com/pathinfo.phps

It also adds a "credits" sidebar using the colors set by the site
owner in the database, so you can probably ignore that.

Pretty much every photo you see on http://uncommonground.com/ runs
through this script, and that gets about a half million hits a
month...

Except the calendar page, where I pre-generate the thumbnails by hand,
as there are so many, and because I want an extreme close-up rather
than just a shrunken blob.

If you're getting more traffic than that, you may want to consider
running a cron job to thumbnail them once -- I don't do that, as we
haven't quite reached the stage where we need that, but you might.
