What happens if you select more than four photos? Lightroom just adds another page (or as many pages as you need) to accommodate the photos you’ve added. Look in the info area at the right end of the toolbar, it now says "Page 1 of 2." If you click the Next Page (right arrow) button in the toolbar, it will take you to that second page (as shown in Figure 9, where I selected three more photos). Note that photos are added in the order in which they appear in the filmstrip. In this case, all three of the photos I added came after the first four I had selected in the filmstrip, so they all wound up on their own new page without disturbing the first page I had already set up. Click on the Previous Page (left arrow) button in the toolbar to return to the first page.
