When we explorer a folder in "thumbnail" mode, in it, if there is some
folders with
pictures, the folder icon change, become bigger, and 4 previews appear in
this icon.

Why is it that all my saved photos appear in the list of Screensavers?  Even
the ones I have deleted from My Pictures file - How can I delete the onesI
don't want? I just feel that to have photos stored in the 2 places must be
using up space on my machine. I run Windows XP2,
