WordPress Slideshow Plugin

I am using a picasa link for the side bar slide show on my home page...but do not like how it doesn't continually rotate and am limited on picture storage on picasa. I want the slide show function to scan multiple picture folders under one major folder on my server. When this slide show is clicked, it opens up a java window with the full screen slide show. The latest picture folder would be either automatically uploaded under the category of Photos or easily done in wordpress and be a listed as Thumbnails similar to what I have with the Picasa plug in. When clicked they would enlarge into java/thumbnails slide show view would be nice. This viewer would open up to the picture clicked on but would display all photos in each separate sub folder category as a user scrolls left or right on the thumbnails. I have one idea of a plugin but if something else works better to meet the requirements stated you are free to use what you are familiar with. If you should win this bid, I will put your money in escrow and will transfer it to you upon satisfactory completion of the project. No exceptions.
