I've got a bug report from the field that essentially boils down to image caching. Namely, an image from the same URL is getting cached and it's causing confusion because the image itself is supposed to change.
My fix is to do this bit here. Which I'm certain will work.
However - I can't freaking reproduce this. I would prefer not to do the methods I've seen here because they require code modification and I'd rather test this on the code as it exists now before I test a fix.
Is there any way in a browser like IE to force it to cache like mad? Just temporarily, of course.
