       diffimg - Calculates intersection between two images

       diffimg image1 image2 [outimage]

       diffimg  generates  an image where each pixel is the difference between
       the corresponding pixel in each of the two source images.  Thus, if the
       source images are the same the resulting image will be black, otherwise
       it will have regions of non-black where the images differ.

       Currently supports: .png, .gif, .jpg, and .ps by using ghostscript
