If you haven't seen Pandora before, it's worth a look. Pandora uses a plug-in architecture to wander the big image search engines (i.e., Google and Flickr) or your hard drive, and supports finding and fetching any type of media -- not just images. Once you've found the media, Pandora provides easy slide show creation so you can show it off. I like the fact that you can start off multiple searches simultaneously and have them run
The Pandora demo is limited to 50 image viewings, and if you love it you can buy it for $29.95.
