how to swipe product image

47 1 11


I am currently using the Debut-theme on my shop and I am struggling to change the following function:
At the moment you can only change the product image in the product page by clicking on one of the other pictures below the current picture. My problem is now that people that are using a mobile phone are used to swipe right and left to change picture and I think this would be much more convenient.

Can anyone please help me to change the code and to implement this function?

Thank you in advance for your help!
