That's very nice, no kidding.
I'm no mod so it's not up to me, but forum rules are max sig size of 500 x 250 pixels.
What I do in a situation like this is to make a new file - file>new - and make it have a 2:1 aspect ratio. I might make it 700x350. Then I'd select the bg layer and copy/paste it onto the new file. Then I'd use the transform tool - edit> free transform -and make the bg fit the new file.
Then I'd start copying my goodies such as bike and pinup etc. onto the new file and transforming and moving them to fit.
hth.
