I would like to prevent users from inserting links to pictures from other websites into my ASPxHtmlEditor control.  I have set the AllowInsertDirectImageUrls property to False.  However, if a user copies and pastes an image from a website directly into the control, it inserts the link to the picture rather than saving it locally on the server, seeming to by-pass this property.  Is there a way to prevent all image links from being inserted without saving and referencing a local copy of the image?
