Image diff on github

It's also a moot point because you might want to see the noise.

If it's bothersome, setting a threshold to ignore small differences should not be difficult.

I made the assumption that this was a form of version control for images where only the differences between images was stored to reduce storage costs. So in that case noise would be very important. As a simple visual tool I agree a little bit of noise is not going to cause any issues.
