Turkish security officials were working to identify the 15 individuals, English-language state broadcaster TRT World reported, adding that Turkish officials believe the Saudis may have taken the consulate's CCTV footage with them when they returned to Saudi Arabia.
The timestamped picture has a Turkish caption bearing Mr Khashoggi's name and that he was arriving at the consulate, but the man in shot has his back to the camera.
A statement on Sunday by the state-run Saudi Press Agency (SPA) cited a diplomatic officer who categorically denied "these baseless allegations, and expressed his doubt that they came from Turkish officials that are informed of the investigation or are authorised to comment on the issue".
According to his fiancee Cengiz, Khashoggi had visited the consulate to receive an official document for his marriage.

Journalists and activists gathered outside the Saudi consulate on Monday demanding information on Khashoggi's fate.
Turkish authorities are set to search the site after announcing that Saudi Arabia had declared itself "open to co-operation" in the investigation, but no date has been announced for the search. This group is considered to have a connection with the disappearance of Khashoggi.

President Donald Trump, who took his first overseas trip as USA president to the kingdom and whose son-in-law Jared Kushner has close ties to Prince Mohammed, said he had concerns.
"If media reports from the weekend regarding Mr Khashoggi's case prove correct, that would be extremely concerning and the UK will treat the incident very seriously - friendships depend on shared values", a spokesperson for the UK Foreign Office said.
