Imagefield formatters don't respect visibility options
Compact view for multiple imagefield

Hack to lightbox2.formatter.inc to hide images that have their "list" attribute unchecked:

// Set up the rel attribute.
$full_rel = '';
$imagefield_grouping = variable_get('lightbox2_imagefield_group_node_id', 1);
if ($imagefield_grouping == 1 && $item['list'] == 1) {
$full_rel = $rel .'['. $field_name .']['. $caption .']';
}
elseif ($imagefield_grouping == 2 && !empty($item['nid']) && $item['list'] == 1) {
$full_rel = $rel .'['. $item['nid'] .']['. $caption .']';
}
elseif ($imagefield_grouping == 3 && !empty($item['nid']) && $item['list'] == 1) {
$full_rel = $rel .'['. $field_name .'_'. $item['nid'] .']['. $caption .']';
}
