I am trying to implement a dropdown menu with images instead of text, i currently have it working using the wp_list_pages function but need to change it so that a new column is selected for the source, so rather than using post_title i have an alternate function called wp_list_pages_images that uses a new db column page_title_image, but i have looked over the functions and have been unable to determine where to make the necessary changes, new to php, any help would be appreciated
