SmartFrame images embedded on the domain you specified as your home site are classed as onsite embedded images. SmartFrame images embedded on any other domain are classed as offsite embedded images.

These two types of images are displayed differently, as outlined below.

Attribution

Assuming Attribution has been enabled, offsite embedded images will display Attribution along their base until mouseover action, at which point they will show a Caption instead (if enabled). Onsite embedded images do not show Attribution at any time.

Design

While you can alter the design of interactive controls on onsite embedded images, offsite embedded images will always show these in the default SmartFrame color.
