A short rough translation:
"Dear Mr. Pritchard
Unfortunately we used several of your pictures on our website without permission, as we didn't know, we had to ask for permission first. We are very sorry for that.
I would like to ask you now for permission to use your fotos on our website www.swiss-va.ch.
I'm hoping for a positive answer
And yes, the request is a free use of your pictures
