The first footage has emerged from the hospital where 12 Thai boys and their coach are being treated after their dramatic rescue from a flooded cave.
Several boys can be seen in facemasks and hospital gowns, at least one giving a victory sign for the camera.
Meanwhile, reports say the boys and the coach were sedated to stop them panicking during the dangerous rescue.
The Thai Navy Seals also released new video showing the three-day rescue operation that captivated the world.
Divers who took part in the operation said the boys were heavily sedated to avoid anxiety as they went through the dark, narrow, underwater passageways.
Former Navy seal Chaiyananta Peeranarong told AFP news agency: "Some of them were asleep, and some of them were wiggling their fingers, kind of groggy - but they were breathing. My job was to transfer them along."
Each boy was strapped to one of two rescue divers tasked with shepherding him, and bundled onto stretchers to be carried through the dry parts.
Earlier on Wednesday, the head of the Thai Navy Seals told the BBC that "hope became reality" with the rescue of the boys and their coach from the Tham Luang cave.
The boys lost on average 2kg during their ordeal but are said to be in good physical condition. They will remain in hospital in the nearby city of Chiang Rai for a week, followed by a week's recuperation at home.
The first four boys have already been visited by their families, officials said, and the others will be allowed to receive visitors soon.
