I like the idea myself very much; however, I have a suggestion or two for the photos.
1. I think every one who post should try and keep the size down to within the size of the screen area so you wouldn't have to scroll to the side for viewing.
I enjoy a large picture but when you have to scroll to view part of it takes away from enjoying it. Most of the pictures I've posted have been about 400 X 300 pixels in size. I think you could go a little larger without edging off of the screen!
2. Could the voting be set up using a poll? If it could then it might have to be on the honor system that you would only vote once. Perhaps Organic Hosting Andy might have a suggesting for that.
The votes could be PM'd to one or two moderators for counting, that way it would be fair.
3. Do the pictures always have to include your coach?
I know I enjoy viewing scenic pictures very much. It would also be a great way for everyone to view different parts of the country where we live, etc....
Great idea I hope it works out!
