If you stitch together photos, sometimes something that crosses the join will be in one image and not the other.<p>I submitted something very like this some time ago:<p><a href="http://maps.google.com/maps?q=(50.333689,-4.149201)&#38;hnear=%2B50%C2%B0+20+1.28%22,+-4%C2%B0+8+57.12%22&#38;ll=50.333689,-4.149201&#38;spn=0.013834,0.038495&#38;z=15" rel="nofollow">http://maps.google.com/maps?q=(50.333689,-4.149201)&#38;hnea...</a><p>Make sure you have satellite imagery turned on. In this case the two overlaid images give you two copies of the breakwater.
