How to add custom board images

1. Open the folder of the game you want to customize
   Example: Chess, Reversi, Ludo, Yacht, PegSolitaire, etc..

2. Add your custom board image as a PNG file

3. The image must be exactly 128x128 pixels

4. Open the board menu in-game and select your new image

Properties files:
- Board folders must keep their .properties file
- The file is named border.properties
- It defines the clickable board border size for each image
- Each line uses the image name without .png, followed by the border size
- Example: Default=0
- When adding custom board images, keep the .properties file from the same folder
- If your image needs a different border, add a line for your image name
- Example: Wooden=4 for Wooden.png
- Do not delete or rename existing .properties files

Notes:
- Do not delete Default.png unless you know what you are doing
- Games with variants or sizes have their own folders, for example Draughts 8x8/10x10 or TicTacToe 3x3/4x4/5x5/6x6
- If an image does not appear, check that it is a valid PNG and exactly 128x128 pixels
