Not that I know of, by ads I meant in-house ads for other titles. I have seen a few occasions certain creators will advertise books they had a part in that were published elsewhere, but those are also (at least partially) creator owned books. For instance Millar regularly puts ads for his Icon books in there.
And just to clarify my previous post, it's not like Image does zero marketing on their own, but where a company like DC will go out of their way to schedule press interviews with various sites and creators at conventions (along with the stipulation that the interview sticks entirely to DC related questions, and a PR handler usually being present), Image isn't babysitting anyone outside of scheduled panels or signings. If a creator wants their book to have more exposure, they've got to put in the effort.
