Windows Picture and Fax Viewer question

I'm running Windows XP (finally) and have grown to like the picture viewer program. However, I was wondering if there was a program that worked just like it, but allowed you to run the program like any other. (Because I can't seem to find the Picture & Fax Viewer program located anywhere on my hard drive.) Also, it would be nice if the program could open files from a menu option, since the Pic & Fax Viewer doesn't allow that. It only runs when you open a picture file, and allows you to shuffle forward and backward from that file's location.
