Hi
You can pass information with the imagetag just fine, eg:
[from w1]
<img src="http://www.w2.com/images/doimage.php?id=762357">
and vise versa
[from w2]
<img src="http://www.w1.com/images/doimage.php?id=762357">
It works the same as GET as far as PHP is concerned.
doimage.php can retrieve the value with $_GET["id"]

I am not sure if you need file for that, but I do not know your setup.
Summarizing:
If you want to pass the value of the cookie from w1 to w2 via an image that
is displayed on the w1 page:
JS:
var cookiename, cookievalue;
// fill them with appropriate values
var theImgURL = "http://www.w2.com/images/doimage.php?";
theImgURL += "cookiename="+escape(cookiename);
theImgURL += "&cookievalue="+escape(cookievalue);
document.images.mycookiegif.src=theImgURL;
<img src="0.gif" name="mycookiegif">
Then from w2 doimage.php:
[php]
$cookiename = $_GET["cookiename"];
$cookievalue = $_GET["cookievalue"];
[not tested, just the bare idea]
Does that help?
