Hello Maris,

No, because by that point the Header has already been sent. You can't
issue a cookie after a header has gone and use it in the same page
session. As the PHP manual so elegantly puts it - this is a protocol
restriction.
Your browser will look for cookies at the start of the page request,
not in the middle of it (where your image is). At that point, the
header is already sent.
