Any reason why you can't use the find and diff commands?
Two nested loops using find (restrict to jpg files) then just do a diff on the two files in the inner-most loop. Make sure that they aren't the same file of course.
Whilst it may not be the most efficient algorithm, it uses tools already available to you.
The other option may be that you create a hash of each file and then compare the hashes. I guess it depends on how big your files are and how many there are as to which you choose to do.
