No ground on any receptacles in my entire house?
From looking at your photo's, I see your main breaker (first pic) is connected up properly, and I am assuming the bare conductor is your system grounding conductor. What I don't see is a properly sized ground conductor coming from the main beaker to your subpanel. It should be attached to your ground bar in the subpanel. That would be the buss on the left and attached to the large lug on the bottom.

So when your subpanel was installed someone pulled two phase conductors and a neutral conductor but no ground conductor. That would mean your panel has no ground and neither do any circuits coming out of the subpanel. 

Needless to say this is not a good situation. In fact potentially dangerous. Assuming this is a 100A service you need to pull a minimum #8 ground wire between the Main Disconnect and the Subpanel. If you want to be safe pull a #6 ground and that would cover everything up to a 200A service. Of course this should be corrected immediately.

Good Luck.
