I'm with UW, I use an ad telling them where to find the images they were looking for. For a hotlink image, I think I'd rather have my ad displayed and possibly generate some type-ins. Also, I have been guilty of fucking up recips on one of my freesites, leaving the wrong domain as the path to buttons, which caused my ads to be displayed on that freesite I subbed instead of the relevant LLs buttons.
Now, if I'd subbed that to a reviewer with those buttons in his cache, and the site got listed (which was actually the case with this particular freesite, another reviewer spotted it and let me know) and his surfers were treated to tubgirl, well, he'd have lost any bookmarkers who saw that sight PDQ as far as I'd have thought. If he then went back to my page and saw that image after a cache clear, then I'm pretty sure I'd have been blacklisted, and I couldn't have blamed them one little bit.
It of course was entirely my mistake, but, as a human (sorta) I'm prone to making them every now and then, which is why I also use a very non-agressive 404 page which just redirects to my root, as well as that text ad as my hotlink image.
Just something to bear in mind
