A ledger board is a large piece of lumber — I believe that these are 4×12’s — attached to the walls with bolts embedded in the concrete wall. Once the ledger boards are up, the beams and joists can be attached to them. In Picture 3, the ledger boards are the dark lumber (since it is mounted on the concrete, it must be treated).
