How do I change the order of the product photos?

Go to Products > View. Search or browse for the product you want to edit. Click on the product name to edit it.

Go to the product images area – you can access that from the top navigation V2 or via the left side navigation on V3.

Click to the left of any product photo where you see a little grid of grey squares. While holding the mouse button down, drag the photo up or down in the list until it “sets” in the position you want.

When finished moving your images, make sure to save the product using the buttons at the bottom right of the screen.
