You can see the problem here.
I have uploaded the images at 2880px wide, and amended the slider code in single-portfolio.php to
$media_gallery = rwmb_meta( ‘sf_detail_gallery’, ‘type=image&size=full-image’ );
$media_images = rwmb_meta( ‘sf_detail_gallery’, ‘type=image&size=full-image’ );
to pull in the images at full size. Additionally, I’ve amended the image size definitions in functions.php as follows;
add_image_size( ‘full-width-image’, 2880, 1620, true);
add_image_size( ‘full-image’, 2880, 9999);
But the slider insists on loading a 1000px wide version of the images, which is then being scaled up to around 1200px with a serious hit on the image quality. Any suggestions on how to get a decent version of the image shown?
