Hi,
1st
the login button is NOT for the protected galleries - it is for the extended features like rotate permanetn, enter captions, delete comments.
I think you mean the "Administration" link!
if you want to do this you have to make your login form! then you have to have the same users in your sql as in my htaccess file (or you kind of use the login page from the admin.
then you have to place the user and the password in the session!
look in the admin\.include\login.php - look line 56 how user and pass should look like)
.
and then you modify the "admin link" - The problem is where the files are uploaded to. if you want to access the upload directly you have to use the action upload and the parameter dir
e.g.
admin/index.php?action=upload&dir=counter
and then rename the admin link in the language file to upload!
