Comment (by ryelle):

 I'm pretty sure this happens when one of the images is not fully loaded
 before the comparison script runs - it looks like `domReady` runs when the
 page is loaded, not necessarily when all the assets are loaded. Switching
 to [https://developer.mozilla.org/en-US/docs/Web/API/Window/load_event the
 window load event] should wait until all resources are loaded.
