Free image viewer, resizer, photo editor and more!

Need something small, easy to use, and pretty robust? Use Irfanview! I used to suggest this to many students who needed a quick and easy yet robust image editing program. Sure Microsoft Image Viewer can do things, but… I like variety! 
 It even supports RAW file format (which is nicely supported in Photoshop CS2, but hey… who wants to pay that much eh?)

 Now, they also have plugins, that allow for alot of neat things.
