Hi everybody,
I just had a bit of a flashbulb going off a few days ago and I thought I'd share it with you.
I work in the Visual Effects industry and we constantly have to compare almost identical versions of the same image. The way we do this, beside a standard side-by-side comparison, is to quickly (but manually) switch from one image to the other, back and forth, so that our eyes can easily pick up the differences (*).
I thought this could be useful to extend the wiki way of doing things to images, especially SVGs. The history interface would remain the same but the browser would put the two images on two different layers, one obscuring the other, and a simple button would allow (ideally through javascript) to swap the two quickly. Of course a standard diff would then be available to inspect the differences in the actual code if the image in question is SVG.
What do you think?
Ciao!

(*) human eyes are excellent at picking up changing details in an unchanging scene. Interestingly, they are also very good at picking up still details in a rapidly changing scene. This is probably due to the first case representing a prey or a predator in an otherwise unchanging landscape, and the latter case representing a static prey or predator in a view with lots of moving features, i.e. leaves and branches.
