Using a mobile phone from his travel rucksack, a walker has been rescued after falling in the Lake District Fells on Thursday.
His friend used the mobile phone to take a photograph of his location, to help the Wasdale Mountain Rescue Team determine where he was.
Richard Warren, team chairman of the rescue team, claimed that the walker sustained potentially serious injuries to his head and arm; therefore they needed to reach him as soon as possible.
Mr Warren said: "The informant with the casualty was unable to give their location and attempts to get him to describe the location proved difficult.
"Eventually he was asked to send a picture of the view from his location by mobile phone."
Rescuers recognised the spot as Broad Crag on the Scafell range and were then able to direct a RAF helicopter to fly the casualty to hospital in Whitehaven.
By ensuring daysacks are fully equipped with both outdoor equipment and communication technology hikers can ensure they are always prepared.
