PC Advisor does not use AV I'm afraid, alan14. We'll just add up the votes for each photo.
If there's one photo you prefer overwhelmingly to any other, however, you can just vote for that one - it's not compulsory to vote for three.
Well spotted on the 'tick as many as you like' thing - that's an automated message that appears on our polls when multiple answers are allowed. But in this case we ask readers to limit themselves to three choices.
Thanks for your votes!
