I've customized the main dashboard screen with links to edit posts, new post, etc.
I've also created new wp menu items for background & header image, but I'm not sure how to link to them without using the admin sidebar?
For example, the background button link shows as http://mainsite/sample-blog1/wp-admin/themes.php?page=custom-background
but trying to add a hyperlink like: themes.php/?page=custom-background ends up with a 404?
Probably something really simple to fix???
