$banner3 = '<a href="BANNER3_URL" target="_blank"><img src="BANNER3_IMG_SRC" alt="BANNER3_ALT" title="BANNER3_TITLE"></a>';
$banner4 = '<a href="BANNER4_URL" target="_blank"><img src="BANNER4_IMG_SRC" alt="BANNER4_ALT" title="BANNER4_TITLE"></a>';
$banners = array($banner1, $banner2, $banner3, $banner4);
