I’ve gone ahead and reorganized the picture gallery so that the initial page is not so confusing. I *think* what you will see is that, whenever I add a new sub-album to any of the albums on the main page, you will see a little “updated” label on the main album for 7 days.
I now have main albums for “Parties and Events”, “Vacations”, etc. Within the albums, newest items are supposed to show at the top – so new sub albums will show up right where you can see them and they’ll have a little “New” label on them for 7 days. Albums and Sub-albums to which I just add new pictures (miscellaneous is like this) will have the new pictures at the top and will show an “Updated” label.
