Magic Fields 2.0 get_image Shows Nothing

I decided to nix my own plugin for custom post types and taxonomies because MagicFields seemed to offer everything I wanted and more – use of custom fields and ability to add them to groups.

But I’m having one problem: nothing shows up when I use get_image in my code! I have been using

<?php echo get_image('book_information_book_image');?>

but nothing will show. I’ve used many variations of the code that I’ve found around the net, and it is just getting ridiculous.

Additional info: The field name is “book_information_book_image”, it is in custom group 2 (under Book Information), and it is assigned to the “post” post type. I have it inside the loop.

I have been beating my head against the wall for over two hours figuring this out.

Am I doing something wrong? At this point I’d appreciate any help I can get, thanks!
