Why does this Local Script not change an Image after a certain amount of time once it is clicked?

**I mean you literally answered your question yourself.

"ImageActivated hasnt been approved from ROBLOX yet because I had just made the decal that is why it is black i think"

I tested it for you. It works, just not yet with those decals.

The code is great. Good job!**

Edit: I'm wrong.

When I went to your video I was puzzled as to why it wouldn't work on my screen at all but it somewhat worked on yours. So I did some research.

I tested it with my decals. I got the asset ID by putting my decals/images on a decal object in-game. That's why I jumped to my answer that I originally had.

To get a real asset ID you go to your link here: https://www.roblox.com/library/4888438209/Images-about-to-throw-die and paste that into the "texture ID" area for a Decal object in studio.

The decal object will then auto-correct to the right ID (it will clearly say it). That is how you know what to use.

Sorry about that.

local Button = script.Parent
local ImageActivated = "rbxassetid://5049442168" -- these are the correct assetid's
local ImageNormal = "rbxassetid://4888438200"
Button.Image = ImageNormal -- this makes it so the image is image normal to begin with 
function OnButtonActivated()
    Button.Image = ImageActivated
    delay(3, function()
        Button.Image = ImageNormal -- the function is last changed to image normal
     end)
end

Button.MouseButton1Click:Connect(OnButtonActivated) -- for some reason I couldn't get .Activated to work but mousebutton1click worked.
