View with PicLens & Show as a slideshow

When I click [Show picture list] the pictures disappear.
When I click again the pictures reappear. I would prefer just having the [View with PicLens]. I have the latest nggallery installed. I have gotten ride of a lot of stuff I felt I didn’t need including german language with the <!– –>> but can’t find “[Show picture list]”

any help would be greatly appreciated, thanks. John
