CompuPic Pro also has a nifty thumbnail page generator and does nice batch conversions. It automatically puts the pics on .html pages, but it's easy enough to go into the thumb page's code, do a "find & replace .jpg.html with .jpg" to change all the thumb links to images only, then drag and drop into a gallery. Now if I could only get my content providers to give me sets that are already in order....
Seriously though, it's a nifty tool with lots of cool features.
