Whenever you place a painting down, instead of it picking a random one, YOU choose which painting you want from a GUI screen that displays all of the paintings! YES, you can customize your kz.png (Paintings) file in order to have paintings with custom images – and it will display them!
- Download and install Minecraft Forge for Server
- Download the GUI Painting Selection mod.
- Drag the contents of the .Zip into your minecraft.jar
