This is one of my most popular drawings if my referer logs are anything to go by. I use a modified version of this drawing to sign cards :)
To conserve my bandwidth I try to prevent hotlinking of my images by using rewrite rules in the .htaccess file for my pictures directory, which replaces an external link to an image with one of the small versions of this image. People are still free to make local copies for use as avatar icons and so on.
