Is it safe to block hotlinking when there is no referrer?
In a way he implied he didn't want any traffic (direct) for images from any of those search engines. He seems to be wanting traffic to his pages from all sources, but he wants the images to be available only to those visitors who come for his pages.
If my above understanding is correct, it would make sense for him to consider separating image file requests from web page requests.
