I don't know enough about setting-up the 'page' to offer any suggestions as to where or how. But, in order to save space, maybe just the Campaign medal ribbon, with a bar marked 1st, 2nd, 3rd for those placings? I think if they were the size of the country flag, probably under the siggy, it might work. The idea of the 'showcase' is good, or a single photo-gallery for all completed entrants etc. The full medal could be shown here.
Rather than use a recognized award or medal, perhaps the ribbons could be symbolic of the subject? For instance, the current GB could use the same colours as the Iron Cross on the ribbon, the PTO could maybe be 'Pacific' blue, with a white wavy line, etc.?
Just a thought!
