I've tried both ImageLabels and ImageButtons but I can't seem to put the image of a sword into a ScreenGui. I've tried rbxasset//99999 and rbxassetid//999999 and a few others, and the image won't display. I'm trying to get an image of the VenomShank into a shop gui.
Use this link, you cannot access a gear image. You must use a decal,
