There are some really good Facebook photo covers and banner images coming out. Take a look through these in this Huffington Post article: click here.
My personal favorite is the image above with The Muppets. As you can see, others in that same slide show leverage the headshot photo space to the left in creative ways that allow it to become an integral part of the larger photo itself.
