I'm right there with the above poster. Why is this so difficult? I want the images I post to show as I uploaded them, full width, no matter what the size of the page is. So inane. Here's a page where I've used the object-fit: contain snippet. Solves the issue, but the section height is static, so the page looks ridiculous on mobile (albeit no cropping). Perhaps there is a CSS snippet to dynamically adjust section height? I have my sections set to 100.
I also don't understand why there is no function to click and view a photo at full resolution. Hence why I'm forcing myself to use a full-bleed slideshow to maximize image quality, independent of device.
