Login-Image plugin option appearing in "super admin"

Hey guys, I've got an issue with a new network im setting up.
I've installed the login-image.php file to the plugins-mu folder
like I did with my other networks, but the menu option under
super admin fails to appear... but shows it's installed under
the plugins menu for mu's.

plugin displaying the Login Image option in the super admin
menu and not...

PS: I noticed that there is a conflict of directions you give for the
