shlomikalfa Posted November 13, 2008 Share Posted November 13, 2008 hi, i have a site in which people can upload URLs to pictures they want to share... but some of the people are uploading links to protected HOTLINKED images which just won't show in my site.... so I'd like to know if there is any way to recognize these NOT-SHOWING - HOTLINKED images and tell the users prior to their upload that these pictures won't work... try uploading somewhere else... Any idea ?! Quote Link to comment https://forums.phpfreaks.com/topic/132562-solved-hotlinks-how-to-identify-protected-urls/ Share on other sites More sharing options...
revraz Posted November 13, 2008 Share Posted November 13, 2008 If they are from the same domain, just check the string for that domain name.

premiso Posted November 13, 2008 Share Posted November 13, 2008 I do not think it is possible. You would have to have image recognition software to determine it. Although the site that is dishing the image may send some type of header with the image, which I do not know if you can parse it out, but yea that might get you something. The only thing I could think of to do, is ask the user to verify the uploaded image if they verify it, post it, if they say no, than dont add it. I would hope a user would not post a blank square image. Sometimes you would hope that users would be smarter than they are.
