The poll would make less work. You post 10 pictures and everyone votes. Thats it. Please see this link for something similar where i visit once in a blue moon:

My question is why are the mods choosing, surely thats up to the members.....?
Also why dont you organise a poll to see where people found the site as that will make for a better understanding of the visitor journeys and where else they are coming from other than just a google search.
I think a bit more interaction is key.
