[How to]Move Image directory to subdomain?

[feastboy]

Hi mate,
i am new to this forum and can you guide me, how to move images to subdomain

In mybb, under the theme option, something like below is there,

Image Directory
The root directory for the location of the images used in this theme. Note that this only specifies the directory for the images used in templates, not the stylesheets.


my images are in theme name def, so image directory is
images/def

now i added subdomain(cookie free domain), so i want to use that sub domain for images

so what are the changes in settings and code needed, that is how can i point the images to subdomain......???

eg:
main domain: mydomain.com
sub domain : static.mydomain.com

Any help is highly appreciated


Note:
this all things are mainly for setuping cookie free domain to increase the page load speed
