How to set iPhone to display contact picture when receiving a new text?

I have the Iphone 4 and was wondering if there was a way for the contact's picture to appear when we were texting.|||The way that i would do it, is to set a picture with the contact in their file in "contacts". That way it should show up during a call and/or a text.|||I don't believe it is possible to have a specific picture come up when you are texting. I know that you can have someone's picture come up when they call you. To do that you would go into contacts, pick a person, select edit, tap the picture square, and select a picture. I don't know if that will help while texting, but it might.
