Reply To: Cannot get srcset to output anything

Hm, I’ve tried this. Re-uploaded my images but still only 1 size is being output in the sizes attribute

Isn’t $image_size = ‘project-full’; effectively saying to use only that image size?

Seems to be the same thing happening with this function:

function awesome_acf_responsive_image($image_id,$image_size,$max_width){

	// check the image ID is not blank
	if($image_id != '') {

		// set the default src image size
		$image_src = wp_get_attachment_image_url( $image_id, $image_size );

		// set the srcset with various image sizes
		$image_srcset = wp_get_attachment_image_srcset( $image_id, $image_size );

		// generate the markup for the responsive image
		echo 'src="'.$image_src.'" srcset="'.$image_srcset.'" sizes="(max-width: '.$max_width.') 100vw, '.$max_width.'"';

	}
}
