Is there a way to get more than one homescreen pic?

Unhelpful, but completely accurate answer: Nope.

 

It would probably be a pain to do, but you could probably do it yourself by taking the 3 images you want make one wallpaper out of them. It would probably be a lot of trial and error getting the stuff to line up proper, but still.

*Edit* never mind it won't work.. I was thinking each homepage moved the wallpaper over a decent amount, but it barely moves.
