Contact Picture Help

[skilledone]

Okay for those of you that know of or use S2U knows when a contact calls, if you have an assigned picture to them it takes up the whole screen. My question is is there anyway to get there picture to stay on the screen while in call with them(full screen) or at least take up the full screen when they call without using the S2U software. I'm using windows mobile 6.5 so I already like the lock feature and would like the picture to at least take up the screen as I've mentioned more than once LOL.
