You don't need anyone to come to your game and help. If you need testers to get action shots, then go to the testing section of the forums. If you mean just like overviews and particular parts of your map, just to show it, you definitely don't need anyone. Just take a few shots of the important parts of your map and the biggest parts of your map. Like an overview, maybe a side view if it's that kind of map, and then just go in and show the most interesting parts of the map. Just try to get most of the map included in the screenshots.
