CDN

Hello,

I have a question about setting up custom sub-domain as CDN for images. I like to set up my site so I can upload images from post or other custom post types to custom sub-domain on my site and show them on my site. There are a lot of CDN plugins but I can’t find this, and short of trying every one of them to see how they work I thought I ask if someone knows of some plugin that can accomplish this.

I appreciate any help.
Thanks.
