To rename, select more photos and rename; you get same name plus a number
for each photo: ex JaneDoe(1).jpg, JaneDoe(2).jpg etc.
To keep it simple, I organize photos in separate folders named by the type
of event, date or whatever other criterion.
Then, I select all photos in the folder and rename them.
That makes for easier backup; I just paste folders on another hard drive
then just add the newer ones.
Of course, you can get fancier w/ tags, photo album organizers and so on.
Vista has such features; just type Photo Gallery in the "Start Search"
box. Also, many pics organizers available to download on the web.
