Installed a new store as a sub domain of another store.

Install went perfect. NO ERROR MESSAGES.

Changed the admin name as recommended in the admin/includes/configure.php file and changed the admin directory name using FTP.

image, button, icon folders permissions are 755 and files are 644

- My admin shows only "x"s & alt tags w/o images for all buttons.
- My store shows only "x"s and alt tags for buttons.
- A test procduct w/image has the same problem "x" and no image.

HELP PLEASE.
