93 Camry leaks coolant

I just replaced my radiator and thermostat a few days ago, and now I am finding that after my car runs for just a few minutes (as in going from one errand to the next), I notice that I am leaking coolant. My reservoir tank starts the day full, and quickly is down to next to empty. Oddly, the coolant that leaks is cold, while what remains in the tank is warm / hot. Someone mentioned that this might be a head gasket issue. I thought it might be leaking from the cap or overflow hose, but can't find much evidence for that. Any thoughts?

It is quite possible that this is the head gasket. To me, it has all the symptoms. Can you find exactly where the fluid is coming from under the car? If you could tell me that it would also help with figuring this out.
