Picture Rating History On Home Page

I've noticed that when I like or heart or laugh or cry at a picture that next time it comes around I'll either like it again or ignore liking it because it's been done before, and I'd find it an unfair advantage or something. So can we perhaps have our records of likes kept for us in the sense of what we rated? Again, it should be an opt-in or know to opt-out feature. It would be useful, I think.
