WPG2 authentication

I’m running WP 2.5.1 & G2 2.2.4. I have WPG2 3.07 installed. I also use Angsuman’s Authenticated plug-in.

All of the photos in my posts are located in a G2 album and were linked to my posts via G2image. When any user logs into the site they are unable to view any of the post photos. Once they have clicked on the WPG2 embedded page the photos appear. This action seems to authenticate them/log them in to G2.

How can my users be authenticated with G2 without having to go through this extra step?
