Thanks for the response, I was able to sort it out. Not sure how I missed that page. I have a few more questions.
1) When I am viewing a gallery how can I get the theme to only show the images from the specific gallery clicked on. It seems to scroll through all the images on the site and not just the post you are viewing. I want the post to loop the images
2) If I edit the theme is it possible to enlarge the embedded google maps?
3) How to I prevent a post from showing on the timeline?
4) what do you think is the best size of images to upload for galleries or backgrounds? pixel dimensions.
