<p>Save <a href="../resources/pass.png">this image</a> to your desktop. Use your pointing device to drag the saved file from your desktop onto the orange box, and release it. <strong>A confirmation dialog must appear, allowing you to choose to cancel the upload</strong>. Refuse it. Pass if nothing happens, or if the browser simply displays the image.</p>
