function LoadWBMP ($imgname) {
    $im = @imagecreatefromwbmp ($imgname); /* Attempt to open */
    if (!$im) { /* See if it failed */
        $im  = imagecreate (20, 20); /* Create a blank image */
        $bgc = imagecolorallocate ($im, 255, 255, 255);
        $tc  = imagecolorallocate ($im, 0, 0, 0);
        imagefilledrectangle ($im, 0, 0, 10, 10, $bgc);
        /* Output an errmsg */
        imagestring ($im, 1, 5, 5, "Error loading $imgname", $tc);
    }
    return $im;
}

Notatka: WBMP support is only available if PHP was compiled against GD-1.8 or later.
