If you want to quickly become aware of differences between two images, you can 
switch between them - human eyes are very good at detecting movement.

Further, some image formats are quite straight forward (like BMP, if I'm not 
mistaken). It should be possible to implement a cropping function. It should 
also be possible to only display the rectangle which is different (with some 
padding). I guess this could be made into an extension to ERT, and images could 
be dumped along with other errors.
