How can we set user rights in advance for those who did signup? so new users can instantly begin with thier right(uploading).

Assuming you've activated the register_user, user_groups (and likely user_login-out) goto your admin section, then the admin tab, then the groups tab. There you can set the default rights for the different usergroups

thats it!
micheall, could you tell me what basic rights do i have to select for a group that can only upload files to a particular album?
2nd thing is that a box for log out appear while when somebody log in but no box for login when not login ....

I'm using zenpage.
is it possible to put a particular album in a page rather than on main page of gallery? If not, then how can I hide album displaying on main page? Please reply

Unpublished albums or images (or pages and articles) are hidden for the non loggedin user or users with no "view all" rights. Please read: http://www.zenphoto.org/2008/07/an-overview-of-zenphoto-users/

i got acrylian

but repeating again:
I'm using zenpage.
is it possible to put a particular album in a page rather than on main page of gallery? If not, then how can I hide(not talking about unpublising) album displaying on main page? Please reply

But not publishing is hiding! Only who knows the direct link will find it. Otherwise you can also password protect an album.

You can put an album into a zenpage only by using this:

Of course only the album thumb.

thanks you for your help

now
1. When a new user signup using registration form, why it redirect to main page, even if password, username or email is not correct. If everything is okay, user can recieved email for comfirmation but no text appear after clicking on submit registration form..
Is it just like that or is there any problem ?

acrylian, with tinyzenpage, I can only put images on Page(zenpage) but not albums.
I want to put the album on a Page(zenpage).

Then you have some work to do using the class methods.

unexpected answer
