(CNN) -- A photo posted online Monday shows George Zimmerman with blood on his nose and lips. His attorneys say it was taken the night unarmed teen Trayvon Martin was killed in Sanford, Florida.
Zimmerman says he shot Martin in self-defense. Martin's attorneys say he was shot and killed "in cold blood."
Prosecutors have charged Zimmerman with second-degree murder for the February 26 killing.
The picture, posted Monday on Zimmerman's defense website, was taken by a police officer, Zimmerman's attorneys wrote.
The state had previously provided a black-and-white copy of the image, the attorneys wrote on the website. "This high resolution digital file was finally provided to the defense on October 29."
A police report from the night of the incident said Zimmerman was "bleeding from the nose and back of his head."
The 28-year-old volunteer neighborhood watchman was driving through his gated community when the incident occurred. Martin was walking through the neighborhood to his father's girlfriend's house.
Zimmerman has claimed that after the two exchanged words, Martin charged at him, knocked him to the ground and banged his head repeatedly against a concrete sidewalk.
Martin's family says Zimmerman attacked the teen, who had done nothing wrong.
Martin's death sparked nationwide protests and inflamed public passions over race relations and gun control, as well as Florida's controversial "stand your ground" law, which allows the use of deadly force when a person perceives a threat to safety.
In August, a new judge was named to oversee the case, after an appeals court agreed to a request from Zimmerman's defense team. The attorneys had argued the previous judge had made remarks putting Zimmerman in reasonable fear of an unfair trial.

George Zimmerman Steps Up Fundraising Trial Expense Money

ORLANDO, Fla. -- George Zimmerman plans to step up fundraising to pay for his expenses while he awaits trial for fatally shooting 17-year-old Trayvon Martin.
The former neighborhood watch leader's attorney said Wednesday that Zimmerman plans to launch the New George Zimmerman Defense Fund next month.
Donors will receive "thank you" cards individually signed by Zimmerman.
Attorney Mark O'Mara said an existing fund has raised $140,000 since last May, but the money it is running a bit low.
Zimmerman has pleaded not guilty to second-degree murder and claims the shooting was self-defense under the state's "stand your ground" law.
A trial is set for June, but a "stand your ground hearing" could be held by April.
George Zimmerman, Lawyers Seek Trial Delay, Release Of Trayvon Martin's Personal Information
Lawyers for George Zimmerman, the man accused of second-degree murder in the killing of Trayvon Martin, have filed a motion requesting that a Florida judge delay his trial and that the teenager's school records and social media posts be released.
In the motion, Zimmerman's legal team says Martin's Facebook and Twitter activity "is discoverable as it is reasonably calculated to lead to relevant admissible evidence." His lawyers have also requested Martin's cell phone information, saying that Martin's communications will help them prepare Zimmerman's defense.
A hearing on the requests is scheduled for Oct. 19.
According to the Associated Press, Zimmerman's attorneys said in their most recent motion, made public Monday, that they expect to depose between 50 and 75 witnesses and that more time is needed to review all of the prosecution's evidence.
Martin's family, through their lead attorney, Benjamin Crump, expressed anger and frustration at any attempt to use Martin's records to turn the tables on what they believe is a clear-cut case of racial profiling and murder.
"Trayvon's parents maintain that his school records and Facebook page are completely irrelevant to George Zimmerman's decision to get out of his car to profile, pursue, and shoot their son in the heart," Crump wrote in an emailed statement to reporters.
"How does George Zimmerman's review of Trayvon Martin's high school and middle school records and Facebook page bear any relevance to Zimmerman's decision to pull the trigger and kill a seventeen year old child? Is this going to be a new legal standard we are setting -- for a murderer to review the school records and Facebook page of his teenage victim to determine whether or not he should have killed him?"
Not long after, Zimmerman followed Martin and a confrontation ensued, during which Zimmerman pulled out a handgun and fired a single, fatal shot into Martin's chest.
Zimmerman was not immediately arrested and from the outset claimed the killing was in self-defense. Zimmerman claims he shot the 17-year-old Martin after a life-or-death struggle in which Martin repeatedly hit his head against the sidewalk and announced that he intended to kill Zimmerman.
But Martin's family and supporters say that Zimmerman racially profiled, followed and murdered Martin, who was unarmed at the time.
The killing sparked national outrage. In the weeks and months after Martin's death, Zimmerman's supporters and conservative websites used Martin's online social activity, in some cases mistaking other individuals for Martin, to paint him as a violent, troubled young man. A white supremacy group hacked his Twitter account and a number of images, many of which were not in fact Martin, began circulating in emails railing against Martin and a so-called liberal media bias.
In the email from Crump, he said, "There was a small group of hateful and racist people, who attempted to destroy [Martin's] legacy, reputation, and image."
"These people hacked this dead youth's social media accounts, his email account, and stooped as low as to plaster the internet with photo-shopped and fake images purporting to be Trayvon," Crump said. "On the advice of counsel, and with the intent to preserve Trayvon's public reputation, Trayvon Martin's parents deactivated all of his electronic accounts."
On Monday night, Zimmerman's mother, Gladys Zimmerman, gave her first televised interview on CNN's "Piers Morgan Tonight."
Gladys Zimmerman said that her son was not a racist and that the media's portrayal of the shooting had unfairly skewed public perception of her son. She called the aftermath of the shooting a "nightmare."
"It felt like I couldn't believe what had happened. I felt that the world had turned upside-down," she told Morgan, speaking from a darkened location to protect her identity.
She apologized to Martin's family but maintained her son's innocence, and stated that even with her son facing the possibility of 25 or 30 years in prison, she believes the legal system will yield a fair result.
"I believe in the judicial system," Gladys Zimmerman said. "I believe from the beginning that he is innocent ... There is justice in America, and I believe in justice."
"I'm deeply sorry for what had happened. It is a tremendous tragedy for both families," she said.
