-First we load an image as a control to make sure we can set cookies:<br>
-<img src="http://127.0.0.1:8000/security/resources/set-cookie.php?name=img&amp;value=PASS">
-
-Then we load an SVGImage to see if we can issue network requests from inside the image:<br>
-<img height=200px src='data:image/svg+xml;utf8,
-<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
