Yes, I've used one or more of these techniques for many years. I'm sure you already know that the last line you use costs you 7k of bandwidth each time an attempt is made to display one of the hotlinked images.
But for others, if you do have a substitute image, the bandwidth to display it comes from your bandwidth. So keep the graphic as small as possible in file size.
If using a Gif as in this example, then reduce the colors. For example the brain bucket graphic can be reduced by 3K just by changing the Gif setting to 4 colors.
Cheers,
