The idea presented is OK, but suffers from the problem that sooner or later your webcam will be updating the imagefile at the same moment your javascript reads it, resulting in a broken image. (zero byte file or no file)
Question: is there ANY way of verifying if a loaded image is broken or not? (and if broken not display it)
My testing indicates that neither of the methods: document.images, image.onLoad or image.onError will work for this . Nor will image.height or image.width help.
Seems that Javascript is not up to the job.
Any ideas ?
