Free Photo Utilities...
FastStone is very simple and is a just a batch processor, not a real photo editing program, Irfanview is much more comprehensive editor / organizer allowing much more than just basic photo editing and third is Google's Pisasa which is a very robust organizer with free web hosting and more.
FastStone Photo Resizer

If you're looking for a fast, reliable, and free way to convert many images at once, look no further than FastStone Photo Resizer. The program outputs files in the most popular formats, including TIFF, GIF, JPEG, and BMP. Besides its batch-conversion skills, the application also can rename pictures in bulk. This program lacks any sort of fancy image effects, but you can make basic tweaks, including cropping, rotating, resizing, and adjusting certain aspects of an image's color. You'll even find a tool for stamping shots with a watermark.
IrFan View
This image viewer and editor is a longtime favorite among our staff, and with good reason. IrfanView is simple, fast, and free for individual use. Upon installation, the app attempts to install two Google programs, but you can opt out.
The program lets you open and edit images, as well as multiple media formats. You can cut and crop images, apply batch conversions, add, sharpen, or blur effects, create panoramas, and change color modes easily. The program continues to add support for an array of file formats and has plug-in support for most image, video, and sound formats, including MP3, AVI, audio CD, and WMA.
Google's Picasa

Picasa Web Albums is Google's Web photo-hosting service. Users get 1GB of free hosting, and images can be uploaded and manipulated using Picasa, Google's free desktop photo management application. Users who want additional storage can shell out up to $500 a year to bump up the hosted space to 400 times the size of the free hosting service.
Much like everything else Google, Picasa is exceptionally straightforward to use, with a tabbed interface offering three options--My Photos, Favorites, and Explore--the last of which lets you browse the public photo library. Next to the tabs, you'll find a prominent Upload button for adding photos to your albums, which you can set to various levels of privacy. Within your albums, you have the option to view a slideshow, share via e-mail, make a collage or movie, order prints, and edit various aspects.
