Problem with user's picture path

Once the user's picture is enabled in the module, when display content the src attribute of the tag img for display the picture not begins with the drupal installation directory but it is related to the root sever, so if your installation is not in the root the image is not displayed.

E.g. the current printed value is "/files/pictures/picture-1.gif" it should be something like "http://www.mysite.com/path/to/drupal/files/pictures/picture-1.gif"
