The 45-year-old actress can be seen in some shots shampooing her hair while in the shower.
The junk removal firm were represented by Phoenix-based agent David Hans Schmidt, who was famous for brokering deals involving compromising, and often highly personal, photos and videos of celebrities.
At the time of finding the photos, he said: "There are some pictures of her showering outside. She looks absolutely gorgeous. And yes, the carpet does match the curtains.
"The pictures were not stolen. When you throw something away, you forfeit that property. We recognise the copyright issue, but US copyright law stops at the border."
When asked for a comment, mother-of-twins Marcia said she couldn't understand why anyone would want to see her naked, adding: "I'm pale and bony, just kind of unfortunate looking all the way around, so I don't see what the big deal is."
The 'Sultan of Sleaze' Mr. Schmidt was found dead in his Arizona home after committing suicide in September.
Shortly before his death, he had agreed to plead guilty in a plot to extort more than $1 million from Tom Cruise for the actor's stolen wedding photos.
