Requesting a code to fix sizes between desktop and mobile

Site URL: https://walrus-drum-amwz.squarespace.com/

On this page https://walrus-drum-amwz.squarespace.com/, my home page, I have a gallery section set to Slideshow: FULL. When viewing from a mobile device, the images are being cropped. Is there a way that with code I can get them to show without being cropped? In full size?

**Please send me your email with your reply so I can share with you my site password 😄

Thanks in advance,

Gallery sections set to "full" are designed to fill a width and height, and will therefore have to crop. 

This code can help with not cropping, but you'll want to have images with the same content aspect ratio and you'll have to be careful of content as that can impact whether this method works.
