Thank you for this method. I just have a few questions. 1. How could javascript reload the image? I'm not 100% familiar with JavaScript really... 2. How could I use PHP to find the width of the image? I was reading up on image manipulation last night but only got as far as creating an image.

Images don't click, and you can check whether new data is available by the size of the returned image (e.g.: 1 pixel, no new data, 2pixels, new data). You will need a small PHP script on the backend that generates the image based on whether the data is available or not.
