How can I check whether someone is using the resources hosted on my website?
I have a website (coded in PHP) and I have uploaded a few images there. I want to know who is using those images on other sites. Normally, the people use image URL to access and display images from my website.
I don't need the code, just need some guidelines. If you can give me some pseudo code, that's appreciated too :P
EDIT:
Seeing the responses, I feel that my question was't well-versed, so to rephrase:
I need the PHP code to check who is using images hosted on my site
Is this possible in PHP? If yes, what should be the algorithm for it? Any coding guidelines?
