Thats the problem Matt, you mods and Stu already have enough to do.
Just had a thought though about possibly using the poll facility on a thread to vote(depends on how many poll options you can add of course).You could have a thread each month solely for entries, and as each pic was added it would just be a matter of adding an extra poll option for that image by one of the mods.That way the votes would be sorted by the poll software and would be far less time consuming for Stu and you mods
