Oh, thank you so much rbarry, works a treat
I was using the Eraser tool but couldn't get it right, no wonder really when i was doing it wrong!!
I was going to attempt to 'blend' the smaller picture in as a top layer but the background on some of them are varying colours, ie...part sky, part tree.
Basically what i want to end up with is a photo of a motorcross rider in action with a seperate pic of his face to the top left or right of the final image
@silversnapper1...no, i had white selected but whilst it erased i couldn't repair.
Thanks again..
Martin
