Is it possible to add logo in Interface Form?

[kuovonne]

Currently the only way to add an image to an interface is with an attachment field or a lookup of an attachment. Currently you cannot add a static image to an interface page. 

Some people have a “control” record with a logo in an attachment field, and the. Link that control record to every record in their actual table, and then have a lookup of the logo.

Okay, so if I understand correctly I can't add static photo (of a logo) at the head of the Form in Interface?

I can only add photos to a records via attachment or lookup of an attachment field?

I don't understand this "control" record.. could you please explain in a little more detail?

Thank you!

I have done this, but it does not really work.
Attachment fields inside interfaces are fixed "tall" and show the filename of the image below. 
It looks very weird.
