[Plugin: Magic Fields 2] output URL to image file (not original size)

I see that I can easily do what I’m asking if I just use a single field group, then give the image field within that group the ability to be duplicated. However, the re-ordering functionality is really needed and that’s not an option when doing it that way.

I’m using this method of outputting the duplicated field groups:

<?php
       $members = get_order_group('members_name');
       foreach($members as $member){
       echo get_image('members_photo',$member);
       }
    ?>

Which works great for outputting the thumbnail image…but I cannot figure out how to get it to output a URL to a custom sized image.

So here’s an update:
I decided to try the code I have used to grab data from multiple field sets from the Custom Field Template plugin. This was successful, however, it only outputs the first and last groups….any ideas??

<?php // retrieve entries with photo_gallery_image prefix
				$sql = " SELECT * FROM $wpdb->postmeta	WHERE post_id = $post->ID AND meta_key LIKE '%photo_gallery_image%' ORDER BY meta_id ASC";
				$data_objects = $wpdb->get_results($sql);
				$project = array();
				$i = 0;

				foreach($data_objects as $data) {

					// the name of the fieldset:
					if($data->meta_key == 'photo_gallery_image') {
						$limit = $data->meta_value;
					}

					$i = ( $i <= $limit ) ? $i : 1;

					if( $data->meta_value != $limit ) {
					$project[$i]["$data->meta_key"] = $data->meta_value;
					}
					$i++;
				}
				//check data
				//print_r($project);

				foreach( $project as $key){
					?>

<?php
$attachment_id = $key['photo_gallery_image_gallery_image']; // attachment ID

$image_attributes = wp_get_attachment_image_src( $attachment_id,'large','' ); // returns an array
?> 

<li>
<a class="group1" href="<?php echo $image_attributes[0]; ?>"><img src="<?php echo wp_get_attachment_thumb_url($key['photo_gallery_image_gallery_image']); ?>"/></a>
</li>    

                    <?php
					// etc....
				} ?>

Hi, in get_image check param $tag_img,

https://wiki.magicfields.org/doku.php?id=front-end_functions_v20#get_image

echo get_image(‘photo_gallery_image’,$my_group,$field_index,0); //this return the path of thumbnail

You are my hero.

Thank you so much for the quick reply!
