Other ways to view photo collages:
Narrow your window if on a desktop or laptop computer enough, and the pictures show up one by one.
Click or tap on one picture to bring up the slideshow viewer.
There is caption describing the picture at the bottom. (Note: I discovered this late, and slowly am going through the pictures captioning them)
At the bottom are arrow controls. Click/tap them, or use your arrow keys/swipe left or right to move between pictures.
In the upper right corner is an icon with crossed arrows. Click/tap it to enlarge the picture. Then use your arrow keys (or swipe left or right if on a tablet)
The Escape key takes you back to the collage, or click/tap on the ‘X’ icon at the bottom right.
On a very small device, like an iPhone, the pictures always show up one by one.
Press the ‘Back’ button in your browser to go back one step to where you came from.
