I just looked up Doteasy, and it says they offer Hotlink protection. Hotlinking is the term that's used to describe hosting an image and then spreading that link around via links and <img> tags.
(but that almost a year old).
Their site doesn't seem to mention anything about hotlinking other than it allows you to link on other sites.
cPanel usually refers to Control Panel or Configuration Panel.
Hotlink protection should be in there...but if it's not, I suggest contacting Doteasy to find out more.
Hope that helps.
