How do I create a thread with a thumbnail, that shows one image, but another one, when it's enlarged?
I have seen this several times, but cant figure out how to do it.
All I know is that 2 methods exist. One is working with 2 images layerd together in PS with a grid and gamma.
However the other method does show two seperate files, one as a thumbnail, and anotherone when enlarged.
Please help (pic somewhat related)
