I don't have a pic handy. What are you trying to find out?
My QT (for smaller fish) consists of:
a bare bottom 10 gallon tank
~ 10 lbs cured live rock
a few snails and hermits
HOT filter or internal (Duetto) filter w/ carbon and biological media
50-watt submersible heater
pH 8.0-8.3
ammonia and nitrite undetectable
nitrate 10 ppm or less
The purpose the QT is to isolate new fish to observe health, eating and behavior. It is important to keep water quality high, and minimize stress on the fish, hence the live rock.
Hospital Tank is DIFFERENT from QT (IMO)
However, if the fish needs to be medicated, I remove the live rock, inverts, biological filter media and carbon. Many meds will know out the biological filter. In this case, you need to keep water quality up with daily water changes, and removal of uneaten food.
Here is an informative thread from the seahorse forum that has a good description and picture of a hospital tank, along with how medication and water treatments are handled:
