Scottish stunt cyclist Danny MacAskill is performing for the cameras on top of Glasgow's Finnieston Crane.
The 28-year-old has been pictured carrying out manoeuvres on top of the 174ft (53m) tall structure on the banks of the River Clyde.
He is filming a three-minute short film at locations across Glasgow which will be shown during the Commonwealth Games.
MacAskill, from Skye, shot to fame in 2009 after he posted a film of himself doing stunts on his bike on YouTube.
The stunt cyclist is expected to do further filming at the Millennium Bridge in Glasgow later on Wednesday.
