I too only just joined today and having only read through this topic and the one at the top of this sub-forum I wonder if another easier way of voting could be utilised. Obviously, I have no idea what has been tried before either.
Each photo in the gallery has a "Report Photo" link underneath it, click that, select "Other" from the dropdown and type "POTW" into the more information box....job done and voted. Members can now vote easier and as they are viewing the actual photo in the gallery.
On the admin side, emails that are received for a reported photo header can be filtered so that those with "Other" go to one location where they can be counted etc etc.
