I am new to Zen photo but like it very much. Can anyone tell me how to remove the "Image Info" link on my large images. This link goes to a pop up window for each image and is not necessary on my site. Also is it possible to add a third column to the thumbnail page of the default theme or at least reduce the white space next to column two?

"image info" You have to remove it from your theme's pages. Please do a forum search, this has been answered numerous times. Also please review our theming tutorial.
