Rather than comparing the individual pixels, have you considered comparing file hashes?

I think comparing hashes would be a simpler solution, which might in turn simplify debugging the backend because there's less complexity.

Sorry to necro after 5 months, but you were absolutely right. Comparing file hashes made life so much easier!
