HOT LINK PROTECTION

Hotlinking is when other people are linking your pictures on their pages or other resources. For example, if they really like the picture you have at http://domainanme.com/wp-content/uploads/2014/07/christmas_nails_by.jpg they can post that URL location on their websites and other resources such as facebook, twitter, etc. If you get excessive hits on that image file that is likely what's taking up all of your bandwidth usage. You can easily enable hotlink protection to prevent this from the cPanel -> Hotlink protection icon.
