It appears though that there isn't a dedicated show function for Overlay so it crashed my IJulia session (ref JuliaLang/IJulia.jl#455) due to the enormous amount of output.

Something like this with a 2000 by 2000 matrix instead of 10 by 10

This isn't a big deal if it weren't for JuliaLang/IJulia.jl#455 because it's currently pretty hard to recover a browser from it. Currently, I'm typing this in Chrome because Firefox is still trying to close that tab -____-

Ah, I now see the existence of OverlayImage. That solves this problem on the Images.jl side for now.
