Activate hover on mobile with touch

Site URL: https://www.semi-circle.co/

I'd like to have the images activated by hover on a computer be activated by touch on a mobile device, so the first click would show the image and a second click take you through to the page. 

Is there a way to do this?

Thanks,

Nick

I've seen the suggestion of adding onclick="" to a hovered element, but not sure how to incorporate this into a Squarespace site?
