OK! You may ask what is this? This is for artist to save their work from being recolored/stolen or something like that. There is two ways 1.) Watermarks (BUT IT isnt that effective. People can still delete it on scratch. 2.) Use www.PicMonkey.com. It is an online editor where you can put texture on it from being easily recolored.
I am not advertising PicMonkey, but it is very good. btw if it tells u to sign up, use your email or ignore it.
