I’m curious if it’s possible to alter image sizes based on device/resolution?
I have a masonry grid of 4 columns which works well with the WordPress medium image size. However when the grid stacks on mobile, I’d prefer to display the “large” image, especially on the later iPhones with their higher native resolution.
I’m somewhat comfortable with css, but I expect I’ll need additional shortcode or php to help with this query?
Additionally, it would be great to specify the “featured post” as “large” too.
