Donna Karan New York apologised Monday for having displayed, without permission, portraits taken by a New York photographer in its Bangkok shop windows.

The fashion house also announced, in its statement, that it was donating $25,000 (RM77,575) to a charity chosen by and in the name of the photographer, Brandon Stanton.

Stanton, who was alerted to the Bangkok display by a fan, wrote a post Monday morning on the Facebook page of his blog "Humans of New York," condemning the use of his photos without his authorization.

The photographer said that, several months ago, DKNY had offered him $15,000 (RM46,545) to buy 300 photos to display in their shop windows around the world, but that he refused, judging the offer insufficient.

"I don't want any money. But please REBLOG this post if you think that DKNY should donate $100,000 (RM310,300) on my behalf to the YMCA in Bedford-Stuyvesant, Brooklyn," he wrote.

By Monday afternoon, Stanton's post was shared more than 35,000 times on Facebook, prompting DKNY's response.

The company apologized, saying the Bangkok store had mistakenly used the images from an internal mock-up.

"We apologize for this error and are working to ensure that only the approved artwork is used," the statement said.

Stanton, 27, launched his blog featuring his photos of people and life in New York City in 2010.

The blog's Facebook page has more than 560,000 "likes."
