Gallery problems – links

Hello. I am using Adventurous, and I have a gallery page. The problems I'm having are the following: 1. Some of the images in the gallery link correctly, and some don't. How can I change this? Did I miss some option when I created the gallery or edited the images? I can't seem to edit the permalink. This does not work: MYURL/gallery/_mg_5813johnny/#main But this does: MYURL/?attachment_id=67 2. How can I get edit or delete the info below the image name? Example: "Published August 17, 2014 at 400 × 267 in JF"
