Decals aren't really even supported in the game yet. Use at your own risk.

1. In Roblox Studio select the brick you want to add a Decal to.
2. Select the menu option Insert -> Object
3. When the dialog box pops up type "Decal" (no quotes)
4. A Decal object will be placed under the brick in the Explorer tree view
5. Change the Texture property of the Decal to be what you want

Note: Decals work best on maps when they are of the jgp type.
