When I set the image of an ImageLabel it doesn't show?

So I'm trying to make a round based game with images for every single minigame. The issue is, when I try to set the image of the ImageLabel, it doesn't show!

Here's the script I tried:

local ids = {
	397558836,
	32348996,
	477764158
}

local chosen = math.random(1, #ids)

script.Parent.Image = 'rbxassetid://'..tostring(ids[chosen])

The problem is that I'm not getting any error message. The Image just won't show. If I check the properties of the ImageLabel, it show that the image is 'rbxassetid://chosenid'.

I'm very confused...

I am not a very experienced scripter. But from what I've seen. When you load whatever game that uses local images and image label. The usual "rbxassetid://" is converted to "gameasset://". Since you can not use "gameasset://" to load your images, just do the following.

local ids = {
	"rbxassetid://397558836",
	"rbxassetid://32348996",
	"rbxassetid://477764158"
}

local chosen = math.random(1, #ids)

script.Parent.Image = ids[chosen]

When the game will start, it will convert the "rbxassetid://" to "gameasset://" and normally, will load the images.

I am not very good at explanation but I hope you understood.
