In the past, I would embed* Google Forms from my Google Drive. The embedded image included a mini version of the form header graphic; it was visually pleasing. 

Now, when I try to embed a Google Form, it shows up as a generic box with generic graphics. 

Please advise!  Thanks in advance, Anne

PS. In the “embed iframe” code menu, I’m pasting the embed code from the Google Form, located on my Google Drive.
