Searching for a picture voting system

[caz!no]

Hello, we are currently searching a picture voting system.
we will use ist only a few month a year.
The reason is, every year we create a printed calendar with the 12 (+1) best cars by users.
is there any addon we could activate for this?
every user should have the option to upload 1-2 pictures and everey user with 20 or more posts should be able to vote ONE TIME.

thank you !
