Interesting idea :)
You can delete people from photos and that's funny. Try to use.
If you want to photograph any great place but there are a lot of people which are in the way, you need MagianFilter. Just take a few, 3 - 15, photos from the one viewport, people should change their position, and upload it to programm and get image without people.
For this MagianFilter has command line interface or pretty GUI, written with Qt. It uses FreeImage library to process images. Currently supports only JPEG format for input and output.
