I made my own. There's a shareware program called "Screen Paver" that i think I downloaded from cnet.com It lets you select an entire directory of photos as the screen shots. Since my screen is 800x600, i just re-size & crop some cool pics from airliners.net and put them in the directory. Now they appear as a screen saver! And this program lets you do different transitions between pictures at different intervals, etc.
Very easy to use.
If you want it email me and I'll see if its small enough for me to e-mail it to you.
