How do I change the order of the photos?
Sort the whole gallery or one section, or drag photos to exactly where you want them.
Sort everything
On the Photos tab, open Sort above the sections.
Pick Name A–Z, Name Z–A, Date taken, oldest first, Date taken, newest first or Upload order. Every section is sorted.
If you had arranged photos by hand, it asks first, because that order isn't kept. Press Sort to go ahead.
Sort one section
Open the section's ⋯ menu, then Sort, and pick by name or by date taken.
Drag
Drag a photo: a line shows where it will land, before or after the photo under the pointer.
To send it to the end of another section, drop it on that section's title, its folded strip or its empty box.
Drag one of several selected photos and they all travel together.
