I have noticed that the maps with a preview picture (during the voting phase) are often chosen over the maps without a picture. For new players a map without a proper picture may seem like a buggy or half-assedly made one so they may prefer to vote for a map with a preview picture in the hope of getting a good quality map.
My question is; is it possible for me or someone else to create a preview picture (even a simple one) for each map? This would make the voting less biased in favor of the maps with a preview picture.
On the other hand, if it is impossible for me (or someone else) to create map previews for each map, would it be possible to remove the preview pictures altogether?
I would like to see other maps played too, not just a fraction of the whole map list.
