Any image seen from within the Milky Way would only be thousands or 10`s of thousands of years old (the Milky Way is 100,000 lightyears wide). Since black holes last a LOT longer than that, it`s safe to assume that any black hole we detect within the Milky Way Galaxy is still there. The farther away you look (other galaxies), the less certainty there is that something you see still exists...but again, black holes last a long time. (longer than the current age of the universe?).
