I've a big problem with image and document path.

I must save it in a folder outside the root, as "d:\inetpub\wwwroot\images\" and recall and write in html by another third level domain, as "image.domain.com/images".

I've searched for tips in all forum, with no solution. My problem is to have an out-of-root folder and call it with another domain.
Please, Adam, help me to find a solution for it. Is good for me the hard code too.... but help me
