A Loch in Scotland

My daughter has been hill walking in Scotland and sent me this picture but no information.  Anyone recognise it? 

Peninsula light has told me it is loch Katerina and the hill was Ben A'an.

I have upgraded my phone and now my old app does not work. I can see the text but not the images- rather defeats the object of blip. I have uninstall and reinstalled.  Still no good.
