I guess that my idea to save webcam shots was not so original...
Mine are listed by date, however, they are just sitting in a big mass of pictures from hikes that I don't bother to look at (all of my pictures just sit in one random collecton -- no grouping whatsoever....how unscientific of me!)
The Whitney pics are one of the few pictures that I have actually looked at several times; I like the idea of making a slide show screen saver with them.
