Here's a few links to very current things that have produced actual images:

One of my favorite pics: http://www.sciencedaily.com/releases/2008/01/080110150936.htm and http://blackholejets.blogspot.com/2011/05/black-hole-jets.html
So far by our best counts 9 of 10 galaxies have supermassive singularities at their cores. Some are active, some quiet, some blowing up real good. Black holes are looking to be one of the primary means by which large galaxies are formed--gathering the matter, expelling matter and shaping the galaxies until they reach a relative equilibrium. Who knew we are all made of star-devourer stuff. 
The second picture in the first post here is a composite where supercomputers were used to take varying wavelength images and then combine them to show motion and scope. The Hubble space telescope was focused through the gravitational lenses (space curved severely by gravity) of opportunely placed nearby stars and a galaxy and the curvature provided by these masses acted as a giant lens added to the Hubble--which allowed astronomers to assemble the pictures--made from actual heat and light observations--that you see above. Sort of like adding a galaxy sized magnifying lense to the Hubble to multiply it's power.
The bright blobs surrounded by dots are the stars/galaxies used to focus and in between is the fuzzy light--that's the gas--and the brighter center--that's the quasar--focused between the gravity fields.
