The commission is seeking images for four categories, which include sea and coast
Photographs of Cape Wrath in the far north of Scotland are to be used on playing cards which will be given to Nato soldiers who train in the area.
The Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) has launched a competition to find a set of 52 images to use.
UK and Nato forces regularly train at Cape Wrath.
Europe's largest military exercise - the twice yearly Joint Warrior - also uses the area.
The first of this year's two exercises will take place later this month.
The playing cards are part of a wider RCAHMS project called Defending the Past, which was launched to celebrate Cape Wrath's built environment, archaeology and environment.
Images have been sought for four categories - archaeology and architecture, flora and fauna, sea and coast and mountain and moor.
The winners will be announced in June and an exhibition of the photographs held.
Local schoolchildren have also been asked to identify objects on the cape's live firing range they would like to see protected from being bombed or shot at.
Objects suggested include defunct armoured vehicles used for target practice by pilots.
Defence Estates and the Heritage Lottery Fund are supporting the RCAHMS project.
