Update - Photograph Tool
That's the photograph tool.
You can now make resizable screenshots of your towns which will become also part of the puzzles. The screenshsots will be saved to the file where the game is inside.
I'm also thinking about to create a kind of ingame photo album with all your shooted town pictures. But I won't try to implement this now. I will probably do this later when I'm far enough with all the other important things.
