That's bogus. A digital logic circuit can't handle more than two items
at the same time, but has little problem with algorithmic complexity.
You only need to visualise one image at a time to interpret JPEG
anyway. It's a really easy algorithm (something based on lempel-ziv
compression, like PNG or GIF, would be much harder, due to the huge
dictionary space).
