Hi! I have a full width image on my website. Squarespace's responsive design cuts off parts of the image on different devices. Anyway to stop squarespace from resizing the image? I just want to keep the full width image as is. Thanks!

I would like the below 2 images to not be cropped when viewed on difference sized devices :

Thank you so much!!! 

It looks like you need to edit the design on mobile (edit the page and the toggle the mobile icon in the top-right corner). When you're on the mobile editor, you can stretch blocks the full width of the screen like you've done on desktop. With the latest version of Squarespace (Fluid Engine) you need to design the mobile page separately and as well as the desktop design.

Hope that helps!
