WP-theme-usage.php

// an example:

// build image gallery
$img_info = image_toolbox_array('horiz-thumb',-1); 

// note: horiz-thumb is a custom format; -1 means we want all images.

if (!empty($img_info)) {
	
  // how many images do we have?
  $img_gallery_items = count($img_info);

  foreach ($img_info as $key => $row){

  } // end foreach

} // end if
