Portrait images shown as landscape on Apple devices

Using the latest Travelify 3.0.4, I have certain images that should be portrait displaying as landscape.
e.g. http://www.treasures-of-nature.co.uk/reiki/
The “candle by crystal” image displays ok as portrait on desktop browsers but on Apple iPad and iPhone it is displayed landscape when tried on Safari and Chrome browsers.
Thanks

Screenshots of the problem are attached. It only seems to happen on my iPad and iPhone. Android is ok.
