Bill Cosby -- Polaroid of Robed Cosby Before Alleged Janice Dickinson Rape

These are pictures of Bill Cosby taken by Janice Dickinson, just before he allegedly date raped her.

Dickinson says she went to Lake Tahoe in 1982 to see Cosby perform. She says the comedian told her to come to the hotel and he'd help her with her career.

Dickinson told ET after dinner he gave her a pill and some wine, and the last thing she remembered was Cosby "in a patchwork robe, dropping his robe and getting on top of me." She says the next morning she was naked with semen between her legs.

Dickinson tells TMZ ... she took these Polaroids of Cosby in the hotel room after she took the pill but before she blacked out. You see Cosby lounging in the colorful patchwork robe, with a 40 of malt liquor by his side.
