PopURL requires the use of a an image in order for users to click on. The image must be placed in the same directory as the applet and must be named "image.gif". I decided to do it like that for the time being to reduce the complexity of the applet. If enough people complain, I will make it so that users can use whatever graphic they want. Some may see a grey area around the image. If you are using this applet, you must adjust the height and width of the applet space within the HTML similar to that when specifying height and width for a gif or jpg image. Click on the image below for a demonstration. Here is the source.
