Image Scaling optimization

I was forced to copy the entire plugin and make changes to the source code. For example for Owl carousel using enjoyinstagram_mb shortcode you could open up enjoyinstagram_shortcode.php in the plugins directory and alter line 76 by setting $entry["images"]["standard_resolution"] to $entry["images"]["low_resolution"]. With this modification I was able to turn Gtmetrix’s grade for Serve scaled images from F to A.

Then there’s lazy loading. I haven’t done it yet, but in theory you could load the images only when in viewport and via JS which should speed up your site a little more.
