For a while, I only had pictures attached to a few of my contacts, which I did just using the iPhone itself. Recently, I decided that I'd like to add pictures to a lot more of my contacts. I figured that it would be easier to do this with Address Book, as the pictures I would be using were stored on my iMac, not my iPhone. I've discovered, however, that all the pictures I added with Address Book just show up as small thumbnails on the iPhone's screen when a person calls, rather than the full screen picture you get with the contact pictures that were added using the iPhone. I've done a little digging on this already, and some people say the solution is to increase the size of the pictures within Address Book. This doesn't make any sense to me though - I don't see any option within Address Book of using larger pictures. Can anybody shed some light on this issue? Thanks!
