I'm trying to remember what the term is when you take one photo - cut it up into lots of images to print at say 6x4 and put the image back together using the individual 6x4s.
I found this which is something like what I'm after but not quite:
Learn Adobe Photoshop Tutorial: Collage Of Polaroids From A Single Photo
If anyone knows the terminology I'm after - my google searches are not useful - it would be most appreciated.
