How Do I Make A Changing ImageLabel?

First off, use wait(). wait() goes at 1/30 of a second. Which is exactly how some movies fps's are. (Frames Per Second.) 1/24, 1/25,1/30 of a second is all frame time. So we can do this:

while wait() do
	script.Parent.Texture = blah
	wait()
	script.Parent.Texture = blahblah
end

but this isn't the best way to do so. Try this, it's an idea:

local frame = 1
frames = {00000, 000001} --Add all the ids here.

function loop()
	frame = 1
	repeat
		script.Parent.Texture = "http://www.roblox.com/asset/?id="..frames[frame]
		wait()
		frame = frame+1
	until frame >= #frames
	loop()
end

Hope this helps!
