I'm not even sure what the issue is here. Everyone is free to post whatever pictures they so wish and there is no limit to the numbers they can post apart from the size and 12 per post limit. The Kirklees Hall of Fame is such a thread that contains a great number of model boats on the water for every one elses reference and interest which could just as easily be of members own boats. Many members post pictures of thier models already and should anyone want to post any more they are free to do so.
I'm not sure what difference a gallery as such will make and the reason there isn't one is probably mainly due to the fact that no-one has suggested it or felt the need for it. A poll seems unecessary and the tone seems to suggest that if there is enough demand then you have a right to one however as with all things related to this forum it all comes down to space and space, as has already been mentioned, costs money.
I think the best way forward, rather than a poll is to start a new thread asking for members to post pictures of thier boats and, if there is enough support for this, then perhaps that could be converted into a gallery in the future if it is seen as beneficial.
