Textures still not loading after given time in script?

Basic script below and question.

while true do
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731287794"
	wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731287911"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288017"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288145"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288266"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288400"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288588"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288727"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731288858"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731289018"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731289119"
wait(0.01)
script.Parent.Beam.Texture = "http://www.roblox.com/asset/?id=5731287650"
wait(0.01)
end

This changes the beams textures and its also had time to load but it still doesn't show up does anybody know why?
