Well I changed it to
add_image_size('maxWidth', 1920, 1920);
to align with the aspect ratio of the medium and large default WordPress sizes. But it never got added into the img srcset. Is there a hook for me to use to add ‘maxWidth’ as an srcset option in the functions.php file?
I see. If the image is not cropped “True” will it keep the original image ratio?
For example is I upload and image that is 1920 by 1500 or will it stretch in/out?
