I've copied all files into the folder said in the readme, but still what picture should I use for it. I can't use the spy picture that came along with it because its a PNG type of a picture, and for some reason mine only accepts JPG pictures.
I registered just to write this. Can you make the spray fade the opposite way? That is at a distance you can see it and the closer you get it fades away. That way someone would see it and chase after the spy only to have it disappear. This could possibly trick them into not knowing that it is a spray.
