Thank you for your quick response. I didn’t notice that.
Can this be tweaked to take a percentage(100%) instead of a pixel? Problem is that on the front end, users are required to upload an image with the width requirements. And with different screen sizes, this would still likely run into visual differences with the header being too small. It would be more ideal to not have a width requirement(a suggested size would be good), but to stretch the images to fit. If the users dislike the way it appears, they can upload something else.
