Yes, I know the collages make for actually terrible wallpapers.  I realized that after I made them.  They look cool, but you'll NEVER be able to find your icons on the screen if you use these as wallpapers.  But maybe you can find a use for them. 

The three collages are sized for different-sized screens, with the resolution listed.  The large photos are all sized for 16:9 aspect ratio monitors.
