    """This widget adds support for uploading images into documents. To support
    this, you must use it on a folderish type (derived from BaseFolder) with
    'ImageAttachment' in the allowed_content_types. Create a BooleanField and 
    use this widget. This will display a form at the bottom of your base_edit
    (presuming it's the last widget, which it probably ought to be) where you
    can upload images into your content type. The boolean field itself is
    used to select whether an image download box should be presented. This
    is similar to the "related items" box in Plone.
    
    Content editors may also reference the images directly in their body
    text.
    
    Caveats: In the edit macro, the upload button may steal the default 
    enter-key-press in base_edit.
