We have an image field on the page content type where the site editor can upload a hero image for each page.
We've been asked to swap out these hero images on mobile for the same image, but with a custom crop specifically for mobile.
I'm thinking we could simply have two fields on each page, one for the desktop hero image and another for mobile.
Can anyone suggest a better alternative? Are there any modules that you know of to address this specific problem? Different images for different screen sizes?
