WPG2 and Galerry Login

I have installed Gallery2 and WPG2 on my blog. All went well and is working relatively good. I’ve even started to style the Gallery2 side. I am battleling to find out how to get the login button to display.

On the gallery page on my wordpress blog – there is no login button as when you go to the gallery directly (outside wordpress)

Is there a way to do this or does the login work from the main wordpress login?

Thanks
