2) Login to your CDN account http://prntscr.com/s4l163 to allow clearing of the CDN cache from admin panel. It looks that you CDN cached a number of old images and still loads them while testing your page.
If you need advanced help with site optimization you can submit the request to WPKraken, they have optimization experts because individual site optimization is outside the scope of our support and we can help only with the general tips.
