Question - I really had trouble figuring out how to change only the background color of my picture. The problem was either my image had been tinkered with so much that I was unable to change it from that point, or I simply did not know how to alter it.

Question - Another question I had was in regards to moving the pictures. I was not able to move the pictures as a whole, but instead moved only pieces of them. This made reassembling them nearly impossible. Any help would be most appreciated.
