Hello,

I’m still not sure what’s going on with the update script, but I found out that there’s an issue with having only a File-Upload field inside of a group, which is how mine is setup. If I add any other input field to the group, the images in the file-upload field are saved and displayed correctly. For example, if I change my code to the following and re-add the files in the file-upload field, everything saves and displays fine, but then I will have a random input field on the screen:

  piklist('field', array(
    'type' => 'group'
    ,'field' => 'featured_images'
    ,'label' => __('Featured Images For Product List Page', 'piklist-demo')
    ,'add_more' => false
    ,'template' => 'field'
    ,'fields' => array(

      array(
	    'type' => 'file'
	    ,'field' => 'images'
	    //,'scope' => 'post_meta'
	    ,'label' => __('Featured Images For Product List Page', 'piklist-demo')
        ,'columns' => 12
	    ,'options' => array(
	      'modal_title' => __('Add File', 'piklist-demo')
	      ,'button' => __('Add', 'piklist-demo')
	    )
      )

      ,array(
        'type' => 'text'
        ,'field' => 'city'
        ,'label' => __('City', 'piklist-demo')
        ,'columns' => 5
      )

    )
  ));

I remember that I set this up this way because if I don’t put the file-upload field into a group, it won’t let me output all of the images onto the front-end.

For example:
If I just use the following code (without a group) and save multiple files in the file-upload field, it will only output the ID of the first image uploaded.

piklist('field', array(
	'type' => 'file'
	,'field' => 'temp-upload'
	,'scope' => 'post_meta'
	,'template' => 'field'
	,'label' => 'Media Uploader'
	,'options' => array(
		'modal_title' => 'Add File(s)'
		,'button' => 'Add'
	)
));

<?php
$temp_image = get_post_meta(get_the_ID(), 'temp-upload', true);
?>

<pre><?php print_r($temp_image)?></pre>

I’ve had this issue on multiple sites, so I know it’s not specific to this project alone. Thanks for your help on resolving this.
