Change an ImageLabel's Asset. How?

This script does nothing, why?

Board = script.Parent.ImageLabel

while true do 

Board.Image = "http://www.roblox.com/asset/?id=51372112"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372116"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372125"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372131"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372137"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372139"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372145"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372148"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372155"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372158"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372162"
wait(0.065)
Board.Image = "http://www.roblox.com/asset/?id=51372165"
wait(0.065)
end 

Make sure you subtract 1 from the ID's.

So, 51372112 would be 51372111

If I'm correct, to change the image its not the word "Image", something like ImageID, I'm not sure. Check the properties of the ImageLabel.
