If someone deep links to an image on your page, don't you owe them as much responsibility as to someone who links to your text? If not, why not?
The point was not the deep linking to pictures, but the use of images, icons etc, uncredited, as part of another site. Say if I found a nice image saying 'home', I can use it in my site design by using an <IMG SRC="http://their.site.com/home_icon.gif"> instead of saving the image locally on my server. This then costs their.site.com the bandwidth. It may not be much in many cases, but the principle is always wrong. Either link with an <A HREF> tag, or save the image on your own server.
