How to Improve or Recover Google Image Search Performance (Queries, Impressions, Clicks)?

[CommercePundit]

I want to improve or recover Google image search performance for my eCommerce website. My website was working well in Google image search but, I found negative performance since implementation of CDN for all images.

Before CDN my image path was as follow.

http://www.vistastores.com/media/catalog/product/cache/1/image/265x/9df78eab33525d08d6e5fb8d27136e95/1/0/10133_1.jpg

After CDN my image path is as follow.

http://lghttp.11720.nexcesscdn.net/805298/images/media/catalog/product/cache/1/image/900x800/9df78eab33525d08d6e5fb8d27136e95/1/0/10133_1.jpg

I can see that, Google image search performance is going down after set up CDN on my website. Because, all images are available on external server.

So, How to recover Google image search performance after CDN or any idea to improve performance?

At SEOmoz we use Amazon CloudFront that allows us to setup a CName for our CDN. For example you will see that all our CDN images come from a few different subdomains, such as cdn.seomoz.org or profile1.seomoz.org. I bet your drop is coming from the ugly url that your CDN is providing. If your CDN allows you to create a clean CName I would do that and create  your CDN at cdn.vistastores.com.
