Lately Mr Price has added interest by taking the photographs in Wanganui locations - the Aramoho Railway Bridge, the tower atop the Durie Hill Elevator.
The page had 11,000 visits last week, with 76 per cent from women aged 18 to 45.
It was not there to make money but to get attention, he said, and he couldn't explain its popularity: "People love it. It's weird."
Sisters Stacey and Alana Denman volunteered to pose because it was a cool idea and a good cause.
"The photos are classily done. It's art. They are modest and very tasteful," one sister said.
