Stornoway police vehicles have been fitted with specially designed car stickers to commemorate the 100th of the Iolaire disaster.
The decals have been designed by local firm Graphite Signs to allow local officers to pay tribute to those who lost their lives in the disaster.
The HMS Iolaire foundered on rocks at Holm, just a short distance from the entrance to Stornoway Harbour in the early hours of January 1, 1919.
The ship was carrying men who had fought in World War I back to the Western Isles. More than 200 people died in the disaster.
Chief Inspector Ian Graham, area commander for the Western Isles, said: “The Iolaire disaster is a hugely significant event in the history of the Western Isles and we are proud to be able to make this small act of remembrance for all those affected by the tragedy a century ago.
“I would like to thank Graphite Signs for producing the stickers, Poppy Scotland for their support of this initiative and Constable Richard Henderson for arranging this on behalf of Police Scotland.”
