Finally how do you detect the hot-linking?
In looking at SmarterStats, there's a report for page views per visit. It shows 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and then more than 10. I could never figure out how there could be zero page views, so I called SmarterStats and they explained that those would be hotlinked images.
I then checked the logs, and saw that page XYZ.html got 85 views on one particular day, and that XYZ.jpg had 235 views.
As for the server, it gives the full size image.
