These pictures are real. I verified them at Snopes. Evidently the polar bear had a full tummy!
"The wolf shall dwell with the lamb,and the leopard shall lie down with the young goat,and the calf and the lion and the fattened calf together;and a little child shall lead them. The cow and the bear shall graze;their young shall lie down together;and the lion shall eat straw like the ox. The nursing child shall play over the hole of the cobra,and the weaned child shall put his hand on the adder's den. They shall not hurt or destroy in all my holy mountain;for the earth shall be full of the knowledge of the Lord as the waters cover the sea." -Isaiah 11:6-9
(on a side note, I believe these verses present a good case for Postmillenialism)
