When someone calls....how do you make the photo show in a small square?

Question

In the commercials for the iphone, when someone calls, the phone defaults to the wallpaper (in the commercials its most often the photo of earth) and the photo of the person is a small square in the upper right corner. When people call me, the photo I've chosen for them takes up the whole screen.
How do I make my phone look like the phone in the commercial?!
PS, I understand this question is pretty hilarious and non at all an important one.

Answer 1

Not silly at all, many have asked.
In general, the answer is....
When you sync contacts from your comptuter, if you are using a Mac or Outlook 2003 (I think) or higher, then in your computer's address book, you can assign an image. Your computer makes (saves) a thumbnail of that contact with your contact data. When you sync, that thumbnail comes over to the phone.
When you assign a picture via the iPhone to a contact, it stores a full screen version of it instead of a thumbnail.
So when a person calls, if the image was from a sync with a picture that was assigned from the computer you will see what you saw in commercials. If the image was assigned from the iPhone directly, then you get the full screen view when they call.
