können Sie die Galerie Shortcode-Funktion in Ihrer Vorlage der functions.php umschreiben und tun so etwas wie dieses
remove_shortcode('gallery');
add_shortcode('gallery', 'parse_gallery_shortcode');
function parse_gallery_shortcode($atts) {
global $post;
extract(shortcode_atts(array(
'order' => 'ASC',
'orderby' => 'menu_order ID',
'id' => $post->ID,
'itemtag' => 'dl',
'icontag' => 'dt',
'captiontag' => 'dd',
'columns' => 3,
'ids' => '',
'size' => 'medium',
'link' => 'file'
), $atts));
$ids = explode(',', $atts[ids]);
$i = 0;
foreach($ids as $id) {
$i++;
if ($i > 2) { break; }
// or replace 2 with how many images you want
$image = get_post($id);
$img = wp_get_attachment_image_src($image->ID, 'post-onephoto');
$largeimg = wp_get_attachment_image_src($image->ID, 'large');
// this is where you output your images the way you want it
$return .= '<a href="'.$largeimg[0].'"><img width="400" height="400" src="'.$img[0].'" /></a>';
}
return $return;
}
