I am using the NextGen Gallery plug-in with the Hatch theme as I am setting up an image gallery site. Everything checks out as mutually compatible but I just cannot see how to marry up the galleries I have created and populated with images, to my main menu. I browsed the database to find out what path had been set up for one of them (it was wp-content/gallery/nature for my Nature sub-gallery) but when I entered this path as a menu item, it merely produced an 'Index of...' (a totally unstyled, plain HTML list of image filenames). I should point out that I am a WordPress newbie, but I do know how to set up menu items for ordinary pages and posts.
Thanks for your help!
