Story highlights Artist Richard Prince took screenshots others' pictures

They have reportedly sold for $90,000

He's been tweeting about the criticism

(CNN) Is it selfie-ish to make a profit off of strangers' Instagram photos?

Richard Prince did just that, and it's drawing a lot of negative reaction.

The painter and photographer blew up screenshots of other people's Instagrams, hung them at the Frieze Art Fair in New York and reportedly sold almost all of them for $90,000 each.

Prince called his exhibit "New Portraits," and the fact that he sold photos without the permission or even the knowledge of many of the original photographers is not sitting well with some people.

Who is potentially worse than Richard Prince? Obviously the people willing to spend $100k on an Instagram screenshot. — ♡ carly ♡ (@carlycarbonate) May 22, 2015

Brb gonna go screenshot some of your twitter profile pictures and sell them for 90k in an art gallery #RichardPrince — Ralis (@ralisdaum) May 27, 2015

"New Portraits" originally went up last year at the Gagosian Gallery, but it was the sale of the pieces this month that has had a negative development for the man who has been "rephotographing" for years, taking pictures of other photographs and altering them.
