xGallery is a Multimedia solution for WP. It's exactly what it should be, a plugin, plug it in and it works :D
You can view it in action here: http://www.evilcoder.net/album.php
There's also an administration backend via the WP Admin

Reworked the GD functions, removed the original code (wasn't mine).
No more borders/drop shadow etc... was more hassle then it's worth.

Fixed a bug that would cause it to only generate 1 thumbnail instead of the whole batch
-- Look for a file manager and a slideshow in the next version!
