I dont have any photos but when I build a hide I try and make it at least two nets thick, normally including a stealth net. A background is also important because when you get up to shoot your bird if you have sky behind you everything will flare away straight away. The times when I've felt the most camoflaged when pigeoning is when My hide is built against a hedge and the sun behind me as you are pretty much invisible then. Also you have to think about space for you, your dog, lunch etc
hope this helps a little bit
