Mass optimizing photos

Hey guys

In your experience, whats the best way to re-size large groups of photos?

I have 400+, and dont fancy individually editing each one.

IrfanView batch conversion

I love it when I can simply post link that exactly answers the question and don't bother with typing explanations. :) Blogging ftw.

If you use Mac OS X you can easily set a script with Automator to do this.

Personally. I use Photoshop actions. Which enable you not only to resize but to apply sharpening to the images after you re-sample them.
