Patching some issues

When previewing a node before insert, i got an error in foreach on line 69.

I changed:

$node = node_load($element['#item']['nid']);

to:

$node = isset($element['#item']['nid']) ? node_load($element['#item']['nid']) : $element['#node'];

If you have a maximum number of images, and only use a few of them, all slots were displaying, the remainder with broken images.
I changed:

$output .= theme('imagecache', $preset, $image['filepath'], $image['data']['alt'], $image['data']['title']);

to:

$output .= is_numeric($image['fid']) ? theme('imagecache', $preset, $image['filepath'], $image['data']['alt'], $image['data']['title']) : '';
