Does the photon's motion cease within a black hole?  If so, does the photon convert totally to mass?  How does this conform with the idea that a photon has no mass when "at rest"?  If a photon is "at rest" when at the speed of light, why wouldn't it just follow the curvature of space time into, and then back out of the black hole while it has no mass?

The photon strikes and is absorbed by the singularity. The energy of the photon is added to the mass of the black hole.

Photons cannot rest.  Your sentence "If a photon is "at rest" when at the speed of light" is self-contradictory.

As long as a photon has energy of motion it has mass according to the De Broglie equations. And the only way to stop it is to cause it to emit all of its energy via Brehmstrahlung.  (Photon division.)

My relativistic physics is a little rusty, but I believe that even in a black hole the light cannot stop moving without ceasing to be light.

Photons cannot takes photographs in black holes im afraid.
If they did they would be spagettihfied , heres how it works : Theres atoms in every object right , If the photon went in a black hole the black hole would pull all the atoms in the photon apart so it would be like jelly kind of .
If we went in a black hole the same thing would happen and we would be like jelly , if we were still alive we could walk through walls !
