I'm just wondering if there is any way to create a JPG file that loads data from the Web. This would allow me to do things like upload a JPG file that shows live data on a Website where the data I want to show is impossible to show any other way. For example, suppose I want to show a random picture on a Website, but I can only upload one picture at a time. In this case, having one JPG file that tells the computer to load a PHP page that then returns any one picture would be useful.
