Suggestions on how to block Safari in iOS from accessing Photo Library, or disable photo storage completely?

We're looking to lock some iPads into Single App Mode where users can access a single page and upload photos without storing them locally, due to security concerns. I can do this via locking them into Chrome and setting the Privacy settings to not allow Photo Library access (so they can click upload -> take photo), but I can't easily deploy the bookmark for the single site without having to do hands-on configuration of each device (either adding the bookmark, or signing it into an account with that bookmark), which would be tedious due to scale.

The ideal situation would be locking Safari out of the photo library, or disabling the ability to use a photo library at all, but this doesn't seem to be possible on the surface. Any suggestions?
