To be honest I'm not the best person to answer this. I would have to 
experiment and I am not near my PC atm.

There is an example file called screen.pov You could try modifying a 
copy of that to see the effect.

You need to allocate myimage to an object (my_object) then use that in 
Screen_Object

#declare my_object =
sphere {
0.0, 1.000000
texture{ myimage }
}


Screen_Object ( my_object, <1,0>, <0.04,0.02>, true, 0.01 )

This will give you a sphere with your image wrapped around it if you use 
map_type 1
