Post pics of maps you are thinking about posting and depending on the rating the pic(s) get decide weather or not to post it (to keep bad map levels down so the rare gems shine through easier) Also makes it easier for moderators to find the maps.
No. Terrible idea. You can't judge whether a map is good or not just by looking at the pictures. You have to play it first. Bad maps? That would just make the person that made the map feel like his map is terrible and probably won't bother to make another one again. Any map should be posted whether it's good or not. The members can give constructive criticism and help the person improve. Thread seems pointless. Might aswell :lock:
I think it is a sorta bad idea and no, you really can't see if a map is good or not till you play it but you can tell if it has potential.You could always do this with your own maps and if you do I'd give a slight description and maybe a full layout picture as well for each.
