The images show him in an auditorium, being pulled into the aisle by his arms as dozens of other officials look on. He was shown being stripped of all his titles. Jang, who often dressed in a trim white general's uniform, was this time in civilian clothes and sitting in the audience, not with the rest of the leadership. Party members watched impassively as two burly men grabbed him.
Jang has already been airbrushed out of other images, while his name has been removed from previous news reports.
It is not clear when the photographs were taken. Unconfirmed reports from Free North Korea Radio suggested he might already have been executed.
The North's KCNA news agency reported after a meeting of the ruling Workers' Party politburo that Jang had been dismissed for a series of criminal acts, including corruption, womanising and drug-taking.
"Jang and his followers committed criminal acts baffling imagination and they did tremendous harm to our party and revolution," KCNA said.
"Affected by the capitalist way of living, Jang committed irregularities and corruption and led a dissolute and depraved life. By abusing his power, he was engrossed in irregularities and corruption, had improper relations with several women and was wined and dined at back parlours of de luxe restaurants."
Andrew Lankov, an expert on North Korea, described the move as the most prominent disgrace of an official in North Korea's history.
"It tells us something about the new leadership's style: the young man seems really tough and brutal in dealing with people he wants to destroy," he told Britain's Guardian newspaper.
Last week, reports in South Korea suggested that Kim Kyong Hui, Kim's 65-year-old aunt and the wife of Jang, might be the next senior member of the regime to be purged. The daughter of Kim Il Sung, North Korea's founder, she is rumoured to be battling cancer, alcoholism and depression linked to the death of her daughter in 2006.
North Koreans and foreign observers will be keeping close watch for her appearance at memorials marking the second anniversary of Kim Jong Il's death on December 17.
The purge of Jang also calls into question how aggressively North Korea will push forward on the ambitious economic projects that he championed. The excoriation of Jang's business dealings is a sign the leadership is uncomfortable with the loss of state control that may come with economic growth.
