Clicking an image while it is loading with follow a link instead of switching image mode

If an image is a link, when you try to click to switch image resize mode, while the image is loading, the link is followed.

I'll see what's the optimal solution but I'd rather not mess with javascript events. Maybe I could remove the href attribute during load. I'll refactor that code to use AngularJS, it'll be a good occasion for a cleanup and adding some unit tests.
