Missing Image Files

[Beachcaster]

Usually, if a web site tries to access an image file that is not available on the server, the missing image displays as a small white square with a red cross in it. This is obvious, but not very professional. Can one use JavaScript to try to load the image, then detect that it is not available (height and width are undefined?), and then display one's own "sorry, try later" image instead. How would one do this?
