All Jevon Jackson wanted was to hang a picture of Jennifer Aniston in his room.

But because his room was a cell at a Green Bay prison, the warden wouldn't allow it. Jackson took his case to federal court, where a judge ruled Wednesday in favor of the prison — but offered the inmate advice on how to get a picture of the TV and movie star.

Jackson, a murderer, ran afoul of the state prison system when he ordered a commercial picture of Aniston, who starred on the television series "Friends."

The prison has a policy against inmates receiving, and thus displaying, commercially published photographs. It adopted the policy in 2006 because of the increasing volume of mail — some 1,500 pieces of mail a day, according to prison officials.

The commercially published photos often contained nudity or other forbidden content such as gang symbols, officials told the court.

Jackson, 30, argued that his First Amendment rights had been violated. He also said it didn't make sense to disallow commercial photographs but at the same time allow magazines that could contain hundreds of images.

Inmates are allowed to display pictures of non-celebrity friends and relatives, as well as photos published in magazines. Neither Jackson nor the prison said there was anything inappropriate about the photo he wanted to display.
