On iPad its too easy. When you're on neighbor airport, press both buttons (Start button/sleep button at same time). The picture will be taken. Then go to your "Pictures", choose it and send it to your email.Screenshots are something I find very difficult, sorry.
Before that, you can cut it / resize it, then you can post it here. Or, like One Bad Day recommend, post a code or game name of that user. Hope he needs more neighbors
