Hmm well you can do it with almost every image editing software, including photoshop, nero snap viewer (or something like that), picasa, etc. Some programs liek picasa make it easier to resize. In addition, if you're posting them here or any other forums, some image host sites like tiniypic have an option to automatically resize the picture upon upload. Hope it helps.
Faststone Image Viewer is my preferred tool for resizing, cropping, changing file types and color editing. It's free, and is also an excellent image viewing program on the whole.
You know...I was wondering...if you work for Pepsi or not Faststone Image Viewer sounds awesome...I'm gonna have to try that out.
