Serving static content from cookie free domain

Question

I am workin gon the recommendation of Yslow and Google page speed to serve static content from cookie free domain.

I have created two sub-domain to serve images and JS and CSS files

static.images.mymaindomainname.com
static.mymaindomainname.com

i have even configured them to point to same domain(alias) and they seems to working fine.I am in a confusion about using these sub-domain to serve static content.

In my CSS file i am using images as images/my_image.jpg and which resolve to www.mymaindomainname.com/images/my_image.jpg and now i have to point this to sub-domain, do i need to change each and every image path with the sub-domain URL like

images/my_image.jpg-->static.images.mymaindomainname.com/images/my_image.jpg

same is the case with JS file and we have many CSS file. Do i need to change path of each and every individual entry? Please suggest

i am using wordpress for portal development.

You can dynamically rewrite urls without touching your current css or js files using .htaccess and mod_rewrite. Check out this post:
