Yes, but the redshift will quickly make the image vanish into the far
long-wave region. I think there are calculations of this in most of
the big GR textbooks, the speed is (I think) on the order of
milliseconds or so for stellar mass black holes.

Whether black holes actually conserve information or not has still not
been resolved to my knowledgle.
