That is one of the features we are in the process of adding, but it's not live yet.  Soon when you upgrade your account all ads across the entire site will be gone.   It's just when you have a free account, we still have to pay for the storage of all of your memories.

With that said though, I took down any animated banners from the baby profile page.  so there shouldn't be anything annoying on there now.  Sorry if it ever was.
