Is it possible to set access feature on the gallery so NON guild members can't view the gallery? If this is not possible could this be a new feature?

No, but I'm going to slide this into the update I'm (hopefully) deploying tonight.

Okay, this change has been deployed.

W00t, yer great! TY much!

How do you enable this?

Non members (unauthenticated people) can see my image galleries...

Admin > Menu Administration. Click [Edit] next to "Gallery" and change the minimum rank to whatever rank you want (currently, it's set to "Everyone")

Yes, this does 'hide' the link to the gallery from the menu, and require authentication to see the 'link' to the gallery, but I don't think it actually protects the gallery.php file....

Yep, I just checked it.... The gallery page is still viewable, as long as you know the URL to it.

There are 10,000 (okay maybe not that many) Dkpsystem sites.... the gallery URL is pretty easy to know....so as long as you know the URL to the gallery, you don't need to authenticate.

Plus it may be in search engines..

How do I make it so you have to authenticate to see the gallery.php page..

Fixed.

Chops, you put other developers everywhere to shame.

Great job.
