First and foremost, I would like to say thank you very much for those who gave me comments and suggestions to my last post. Here, I found two ways how you can prevent someone from hotlinking your files and eating up your bandwitdh.
1st Method – CPanel HotLink Protection
If you use CPanel, you can set and block peoples from hotlinking your files with HotLink Protection option. Just login into your CPanel and click on the HotLink Protection icon. In the HotLink Protection page, you can set which urls you allow for access, file types that you want to protect, url to redirect the hotlinked files and option to allow direct request.
For more clear view about this, I have prepare you with a flash video on how to use the HotLink Protection option. I found this video from my hosting provider FAQ page.
