Image Label not loading in roblox image. Help?

When i make a instance that is a image label i make the things. But the problem here is that when i put the image inside the image label like the link it says failed to load. This would be the link im using to make the image look like this ~~~~~~~~~~~~~~~~~ https://web.roblox.com/library/1039486400/heavy-plus-sign-2795

. It says failed to load for some reason

Put this in a script in the image label:

script.Parent.ImageId = "rbxassetid://1039486400" --Edited

Hope this helps!
