Victoras, very nice. I went that road too, I did a srcOrReverse and than I wanted to test the maskdata for non transparency (would reduce the amount of data by 8: not comparing 2 pictures and then just working on one byte for each pixel. Did not get the Alpha channel working. Would have been interesting for large images.
If you are interested: in your 2 images there are 25920 pixels that are different and it took me 90 milliseconds to find out. Thanks to Bill's algorithm.
