Select the page you want to view, then select either PDF-1 (landscape) or PDF-2 (portrait) and you can view it in the pdf format. You will find it on the right side of the menu line. If this isn't the page you want, backup to the photo page and select the right arrow to the next page and select the PDF again to view. The great thing about this is that when you find your page and save it, at the top of the copy is the citation information already made for you. This is a lot easier and faster for future tracking and citing the information you find.
Hopefully the bugs will be worked out at the website so searching will again be easy but remember to save in the PDF file with the citation.

Good luck in the search for your Norwegian ancestors.
