<p>This test verifies that an image which is prefetched, and which is also contained as a
subresource of the current document can be loaded correctly as a subresource.  See
bug 49236 in which this wasn't working.
<p>When this test succeeds, you'll see an image of Nick on a sailboat immediately below
this text.  When this test fails, you will see no images at all.
