Let’s try this.

1. Click the insert image button.
3. 
    In the URL field, if the path is relative path (/Uploads/j0262681.jpg, or ../Uploads/j0262681.jpg), after postback, you will get a relative path.
    In the URL field, if the path is full path (http://cutesoft.net/Uploads/j0262681.jpg), after postback, you will get a full path.

Hope it helps.
