Sony Ericsson K790 / K800
zooming images not taken by camera
Does anyone know how to get the zooming function of the phone to work when using foreign images (jpgs transferred onto phone). I put a decent sized jpg onto the phone, and while it displays a single version that fills the screen, it does not allow zooming, like what you get when you take a picture and can change magnifications (1x, 2x, 16x, etc)
