is it possible for JavaScript to replace empty img src's on the loading of a page so that you can leave multiple img tags blank and then have an image that says 'image unavailable' and then onLoad of page, replace the empty tag with the URl of this image?
say a function that searches the images array for empty src and then replaces them with unavailable.gif?
