Welcome to WebmasterWorld Guest from 188.8.131.52
If you have a CPanel be very careful if you use hotlink protection
If so I have code which will stop hotlinkers but also allow Google, Yahoo and Bing access to spider your site.
Do people really come to the site
BTW, Facebook doesn't hotlink, because it copies & hosts your images on its own servers.
Why does Facebook appear in my server logs?
Facebook allows its users to send links to interesting web content to other Facebook users. Part of how this works on the Facebook system involves the temporary display of certain images or details related to the web content, such as the title of the webpage or the embed tag of a video. Our system retrieves this information only after a user provides us with a link. You may have found this page because a Facebook user sent a link from your website to other Facebook users.
