One technical limitation of this script to note: Notice the Math.random() usage at the end of the image. This is used so user's browsers will not used cached versions of images by appending a string of characters to an image's HTTP request. Servers will usually ignore this.

However, this method will probably not work if you are grabbing an image from a program, such as a CGI script, that is dependant on command lines (or 'query strings'). CGI scripts are commonly used to pull random images from a database, as is the case in many webcam directories.

Keep this in mind before intergrating this script. :)
