[Plugin: File Gallery] featured images

Hello,

I have several images attached to a post. What I would like to do is to create a custom html for all the images in a way that featured image always appears first and is of a bigger size than all other images.

I’ve noticed that when you mark an image in File Gallery as featured it doesn’t necessarily appears first.

I’m using the following code within a template (see below), so that I can go through each image and create custom html for them.

How can I make sure that a featured image appears first and is of different size, and potentially have a bit different html? Do I need to make 2 separate calls to file_gallery_shortcode function?

$images_args = array(
  'order' => 'ASC',
  'orderby' => '',
  'id' => $post->ID,
  'columns' => 3,
  'size' => 'thumbnail',
  'link' => 'attachment',
  'linkclass' => '',
  'imageclass' => '',
  'rel' => 1,
  'tags' => '',
  'tags_from' => 'current',
  'output_type' => 'array',
  'output_params' => 1,
  'attachment_ids' => '',
  'mimetype' => '',
  'limit' => -1
);
$images = file_gallery_shortcode( $images_args );
foreach($images as $image) {
  <my-html-code-per-each-image>
}

P.S. would be great to have a more detailed description for file_gallery_shortcode function (what can be used in ‘orderby’, what do ‘columns’ mean) for beginner programmers 🙂
