If you click on the thumbnail it will enlarge and then you can navigate through all the photos using the arrow keys on your keyboard or the arrows on the photo itself. The photos are free if it is for personal use, but not if it is for commercial use. Contact me for a licence for that.
Do not click on the buy option otherwise, you will go through Paypal and they charge for that service. Just send me the number at the bottom left i.e. Ingleton dog agility 231 etc. I will then send you a full-size hi-res photo with no watermark.
