Picasa
This is a nicely done web site for a neat image viewer application which is a take-off of Apple’s iPhoto program. Currently the program is pretty neat, you can download a two-week trial version. Some things to note about the program: when you rotate images, or make other changes it doesn’t actually modify your images… it stores the information in .ini files. It works fine but as far as getting your original pictures modified you’ll still need Photoshop.
