Oh, what a boy will do for fashion!

A Ohio college student obsessed with fashion photos has confessed to hacking into Conde Nast’s computer system to sate his lust for hundreds of pictures of models, celebrities and other pretty things — which he posted on his blog and elsewhere on the Internet.

Ross Ulrich, 22, last year stumbled across an image of a then-unpublished December 2009 cover of the publishing giant’s W magazine — featuring actress Demi Moore — which he uploaded to the style Web site The Fashion Spot.

Ulrich’s naughty habit not only nabbed him two federal copyright-infringement lawsuits — but also an FBI raid on his Columbus home, The Smoking Gun Web site revealed yesterday.

Ulrich told the Web site that in addition to scooping up unpublished images from Conde Nast’s servers — which contained Vogue, GQ and Lucky magazine shots — he also hacked into the Warner Bros. studios’ computer network to download clips and still photos from movies that were in production.

He said that he had paid Conde Nast $12,500 to settle its copyright claims and that he believed Warner Bros. had abandoned its lawsuit against him.

Asked why he engaged in online photo poaching, Ulrich said that he wanted to be the first to post the images on the Web and that he had used a simple Google search to find the addresses of servers with weak security.

Ulrich said he admitted his actions to FBI agents when they executed a search warrant earlier this year at the home he shares with his dad, Steven Ulrich, a former New York City cabby who is now a small-business coach.

When The Post contacted him on Facebook yesterday and asked to speak with him, Ulrich wrote back, “Will there be any compensation for an interview?”

He didn’t respond when told there would not be.

A spokeswoman for Manhattan federal prosecutors declined to comment yesterday, noting that there was no pending criminal case against him.

An FBI spokesman for the Columbus office also declined comment.

A Conde Nast spokeswoman did not respond to a request for comment. Warner Bros. had no comment.
