    Update render module of centos-art.sh script.
    
    - Previously, image and palette functions were using the array
      variable SOURCE to retrieve information about source files. However,
      they both fail because the SOURCE array variable was renamed to
      SOURCES. This update changes the image and palette function to use
      the SOURCES variable instead of SOURCE.
