I think researchers are working on this very thing, and it seems like the brain does store "visual representations" or at least it can't be ruled out at this point.
And of course, why wouldn't the brain store a visual representation of what you remembered. That would be the easiest way to store and retrieve it, which is why we do that on computers as well.
