Images on a subdomain

If i have a website say **https://www.mywebsite.com **and a subdomain images.mywebsite.com, is there a way to call images from this subdomain instead of images/ folder?
I know images subdomain use images/ folder anyway but I want them to look like coming from another server and I don't know how to set this up in anywhere. I tried to change admin/includes/configure.php line that says

define('DIR_WS_CATALOG_IMAGES', HTTP_CATALOG_SERVER . DIR_WS_CATALOG . 'images/');

to

define('DIR_WS_CATALOG_IMAGES', 'http://images.mywebsite.com/');

but didn't work. I think this is specific to admin pages anyway.

I tried changing /includes/configure.php also.

Is there a way to use subdomain for images?

Thanks in advance.

Hi...

changing

define('DIR_WS_CATALOG_IMAGES', HTTP_CATALOG_SERVER . DIR_WS_CATALOG . 'images/');

did not work because that define statement requires a folder on the server and cannot use a web address in it's place.

You could name the folder something else if you like. Something like photos/ or products/ but that won't make it look like the images are coming from a different server. but then "images.mywebsite.com" doesn't look like a different web server either since it still has the same domain name. :-D

Perhaps someone else can offer more information.

Maybe you could explain why you would want to do this. There may be other ways to achieve your goal.

no specific reason. I just want the address be seen as if coming from image.mysite.com instead of from subfolders. looks like not possible.
thanks for your time anyways..
cheers
