When editor used in automaticaly created subdomain, it fails to find right image and files paths.

Fo example. Main domain http://domain.com, subdomain http://woman.domain.com. When it working on subdomain, it finds path to upload and look up pictures like domain.com/Images instead of woman.domain.com/Images

 

I was tryind to change PHP variable $_SERVER['DOCUMENT_ROOT'] but it makes no changes. Can you help me?
