The whistleblower posts the the first proper picture of herself after seven years in jail.
Chelsea Manning celebrated her freedom earlier this week by setting up an Instagram account and posting for the first time on the social media platform.
The former US soldier was finally released after President Obama commuted her sentence back in January just before he left the White House.
“Okay, so here I am everyone,” Chelsea posted alongside the picture.
It was her fourth post on the platform through an account which has already been verified by Instagram.
Manning was arrested in 2010 after she released more than 700,000 classified State Department secret military documents to WikiLeaks.
She was sentenced for violating the Espionage Act in August 2013, after the documents were shared online and with major news organisations.
Manning attempted suicide twice during her seven years in prison, and had to spend time in confinement after one of them.
She was originally arrested as Bradley Manning, but publicly came out as a transgender woman in a statement from her attorney in 2013.
Last September she went on hunger strike after demanding gender confirmation treatment, and was eventually given her request by the Army.
“Now, freedom is something that I will again experience with friends and loved ones after nearly seven years of bars and cement, of periods of solitary confinement, and of my health care and autonomy restricted, including through routinely forced haircuts,” Manning said in a statement last week.
“I am forever grateful to the people who kept me alive, President Obama, my legal team, and countless supporters.”
