I'm having trouble parsing what you are trying to do.

When a web server sends out a page in response to a browser's request, it includes a header (which can include cookie information, among other things) and the body (which includes JavaScript). The JavaScript is run by the browser, but AFAIK can't touch the cookies. The body may include image tags, which the browser can choose to follow by asking the server for the corresponding image files.

What are you trying to accomplish? Tell us that, and we can probably suggest some ways to do it.

Update: Corion tells me that JavaScript can indeed touch that domain's cookies. Cool.
