Okay, I hope I can be clear with this, because I'm getting nothing back from Google and Apple's support pages... Under System Preferences > Desktop & Screen Saver > Screen Saver there is a 'Pictures' tab on the left and a large selection of themes. There are some awesome pictures there, and I'd really like to use some of them as desktop pictures, but I can't seem to find the source files. Anyone know where these files are located? I tried searching, but couldn't find them... Help would be awesome. Edit: I'm operating on Leopard.
