When I copy the id only, it works.
There’s no code for us to review, but to answer. You need to include rbxassetid:// with the id as well, or better yet, you use this url
"rbxthumb://type=Asset&id="..id.."&w=150&h=150"
Where id is the id of the image you want to display. You can’t just put the id only, that only works if you’re doing it from the properties
Use the url I gave then and switch id with the id of your image, you’re probably giving in a decal id instead of an image id, hence why it doesn’t work, also remove the rbxassetid:// from the image id you’re giving back
Could it be that there you are giving Image ids and in your current game you’re giving decal ids? That’s the only thing I could think of that’s causing it
So basicly, game is owned by me and my friend uploaded decal ids.
