Hmm, this could be very easy or very difficult depending on how good the "enemy" algorithm is. What image format is being used? Are random bits being turned on and off, or are lines being drawn across the whole image? Is there fluff material at the edges or corners? Etc. The human brain is far better at pattern matching than any algorithm ever will be.
