I will reiterate: working with a grid of pixels is really really dumb. Relatively small tweaks, such as sliding the image to the side, produce huge amounts of error. By our standards, the displaced image is very close to the original. To a pixel-difference-er, they are barely the same image. This makes life hard for a GA. The correct choice is to use a representation that does not get caught up in little localized details. Some people use a 2D Fourier Transform, but I prefer the 2D Haar Transform. It works very well for matching similar images. For a practical application of this, check out the Imgseek photo manager.
