Anki on the Ipad

I'm restricted to using an iPad, the software is fully up to date. I'm using the paid version of Anki on it, while I can add images hey are well oversized but cannot find a way to resize images so they will look more in proportion and not overshadow the information on the card.

Any suggestions would be helpful. I've just restarted using this program and can't remember if I can use the various add-on available for Anki

Thanks for any help offered
