Can't get cookie while processing an image request?

I found the solution.
So I'll post it here for everyone who stock with such a thing in future.
You need to specify in the HTTP header that IE is allowed to send those cookies to hitrd party web sites.
Search for P3P and it really works.
You need to simply add a .htaccess file.
Let me know if you need further help.
