How to smooth out gif animation?

I have a gif and would like to smooth it out, here is the code, I assume its the wait or the texture changing it, which causing a flashing effect? Thanks!

Code:

 local clickdetector = game.Workspace.button.ClickDetector                                                                              



FPS = 6.25
IDs =  {2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023595,2995023715,2995023780,2995023836,2995023903,2995023780,2995024021,2995024077,2995024141,2995024191,2995024260,2995024323,2995024391,2995024446,2995024503,2995024564,2995024620,2995024684,2995024733,2995024795,2995024846,2995024910,2995024979,2995025036} --Insert your image IDs here (Comma separated)
local sound = Instance.new("Sound", game.Workspace.VP.Part)
sound.SoundId = "rbxassetid://2989110083"
sound:Play()

    for N,F in ipairs(IDs) do
    game:GetService("ContentProvider"):Preload("http://www.roblox.com/asset/?id="..F) -- This preloads each decal, so you don't have to deal with flashing decals.
end

    function play()
    for N,F in ipairs(IDs) do
        script.Parent.SurfaceGui.ImageLabel.Image = "http://www.roblox.com/asset/?id="..F 
        wait(1/FPS)
    end

    end


clickdetector.MouseClick:Connect(function()
    play()
end)
