Above is an image that you can create. Simply open the image in your picture viewer, take a picture of your computer screen and don't delete it from your camera when you download the photos. If your camera is lost and an honest person finds it, the first thing they will do is look at your pictures to see if they can get a clue to your identity. How easy is this?
If your camera is stolen, this will not help you. I like to think that most people will want to return the camera to you.
So, you can make a cute graphic if you want (OK, I'm a geek so I made a cute one) or if you don't have a graphic program, or don't know your way around one, just type up the information in your word document. Make your text nice and large to fill up the page and take a picture of that page. Not familiar with word documents? Take a large piece of paper and write your info on it with a felt marker and take a picture of that.
So, if you lose your camera and an honest person finds it, you will have a better chance of getting it back!
