The only ones PSA would have images of are the ones that have sold at auction that they're tracking through Auction Prices Realized or if people upload them to their website for a Set Registry. Maybe in an old SMR magazine article if someone allowed them to be photographed.
Other places to check: worthpoint, Sports Collectors Daily, PWCC marketplace, VCP, Google, etc.
