Favorite Pics Photos and Videos

hello

i need help understanding how the contents work.

what determines your rank ? Because the top few end up being the winners because they are the topped ranked correct ?

Now what and who determines someones rank ?

I had always thought it went my the number of "HEARTS"

your picture got.

but clearly i am wrong.

so what determines the contents rank

and what does it mean when your picture has a say 100 Hearts next to a picture. Is that how many people liked it?

Does that have anything to do with rank?

I would play more but im confused.

thank you
