I viewed the journal page on my PC laptop. It is ''tight'' on the screen for the photo line up, but does fit. All photos are seen
May be the way Safari browser displays the page on this monitor for the Mac Mini , the page with photos displays fine.
the 5 to 6 photo display change, I guess that is a question for Jon or Richard / Helena.
Dont worry how old you are... it is the mileage on your body that adds up.
