Thank you John.

I've added my cloudfront links to GWT and verified them. I will setup cNAME too with CDN to improve my Yslow score.

Also for the K2 Images there are special exclusions for the Robot.txt that are important to add:

# Allow Google Images to spider the images folder and K2 images
User-agent: Googlebot-Image
Allow: */images/banners*
Allow: */images/stories*
Allow: */media/k2/items/cache*
Allow: */media/k2/galleries/cache*
Allow: */media/k2/categories*
Allow: */media/k2/users*
Disallow: */administrator*
Disallow: */cache*
Disallow: */cli/*
Disallow: */components*
Disallow: */images*
Disallow: */includes*
Disallow: */installation*
Disallow: */language*
Disallow: */libraries*
Disallow: */logs*
Disallow: */media*
Disallow: */modules*
Disallow: */plugins*
Disallow: */templates*
Disallow: */tmp*
Disallow: */xmlrpc*
Disallow: */404.html
Disallow: */404
# Optional - use to prevent spiders from seeing search pages:
Disallow: *&searchword=
#Disallow the print view of the component:
Disallow: *&print=1
