As long as you have a valid subscription at Archion you can view the images of each and every church register which is online available at Archion.
You browse thru the available images either by using the left and right arrows above the image thumbnails/previews in the bar on the left, or you simply click on an image thumbnail/preview in the bar on the left and the full image will be displayed right in the center of the viewer.
In case you choose a screen layout without the preview bar on the left, you'll find arrows to browse from image to image right on top each shown image.
Other than that I have to admit that I don't understand what you mean by "pages within that group"? Sorry.
