Noo.... It doesnt matter what colour background or picture... but it is better if they are sinilar like:
On my Justin Timberlake one.. i chose a photo shoot where the pics are nearly the same and because the bcakground it pretty much ice.... You can blend them together so they all end up like one picture...
and then actaully for this one..
I did..... something to do with levels...... Ill tell you later... and ill make a new banner and try explain for you .... i have to get ready for rugby now.
