How to set a downloaded photo as a panoramic?

I downloaded a panoramic photo for ios 7 iPhone 5 but i can't put it in my panoramic folder

FYI, you should register your UDID as soon as possible if you haven't already. Apple has been disabling devices running unreleased software unless you register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and I haven't had any problems with my 4S.
