Use the menu above to go to the gallery you want to view. Then you can use the arrows on the right of the photo to go forward or on the left to go back. I've added some video of this and some previous trips to Miscellaneous -> Video (can't add video to photo galleries).
To see a map of where the photo was taken, click on the three bars in the lower left of thee photo. You can use the default or satellite map. GPS data doesn't work with the Russia photos and is mostly missing from Baja California
On every page but this one, there is a navigation trail (breadcrumb) in the upper left of the page, under the Smugmug logo You can click on the home icon to get back to this page or the name of a previous page to go there.
The family history galleries are still password protected. However, with this software, every photo gallery in a folder is individually password protected. So, the first time you enter the password, click "Yes" when your browser asks if you want to save the password. That way you won't have to keep entering the password when you want to enter a gallery.
In February, we took a National Geographic Expedition to Baja California and the Sea of Cortez. There was no guarantee but a reasonable chance that we'd see some whales. Wow. We saw a lot of blue whales, gray whales (including a baby), dolphins, sea birds and some mobula rays (doing backflips). There were some beautiful sunrises and sunsets, wet landings for a hike or walk on a beach and some walking around in Loreto, La Paz and San Carlos. The weather, food and people were very nice. We enjoyed the trip.
There is some video of whales and dolphins in Miscellaneous -> Video.
