I have a 2 years old WordPress based picture website. Now I am planning to use CDN for my website. But the problem is I have to move my picture folder to a subdomain.

example.com/pics/yyy.jpg and have to change it to
Since the pictures play vital role in my site's SEO I am afraid to change the folder path, but at the same time I am getting more number of hits eventually. Should I compromise my site speed for SEO or the impact would be less if I try CDN?
