The Admin Image Directory should point to your /templates/images folder
where all the images for the Admin Control Panel are stored.

It is the relative path from your site's root, which means you do not
enter the domain name. (just enter the folders that are AFTER your domain)

e.g.: www.mysite.com/locator/templates/images would
be entered as /locator/templates/images.

Please go back and try again.

Error Details: A search was performed to locate the
btn_next.gif file that should be located in your /templates/images folder,
but could not be located. This error can also be caused if you have not yet
uploaded your images into this folder.
