Haha, you’re experiencing basically everything I went through.
This is because the user type isn’t allowed to access the WP uploader. Only admins are by default. I changed my site to allows editors to use the WP uploader. If you intend on logged out users being able to upload stuff through the WP uploader… well, be careful.
Would like to hear Elliots opinion on allowing general public users access to image/file/gallery fields on front-end forms.
