Ted Patrick gave a more in depth info on the subject check his blog here.

The new Adobe Media Gallery engine adds Flash and HTML gallery creation capabilities to Adobe Bridge CS3.Any file that Bridge can preview can be included in a gallery. Finished galleries can be uploaded directly from Bridge via FTP.This is just great it you want to for example show some work to your client via your website without the need of taking too much time in it.
It’s a great engine here’s one I made In about 10 minutes including the upload ( the most time I spend it selecting the pictures =) ).

Anyway here’s what you need to start building Your own:
1.- Update to Bridge 2.1.
2.- Download and Install from Adobe labs.
3.- Start Building your gallery.
