Drag photos here, or tap to choose Add all of an item's photos, then tap Front / Back / Solo on a thumbnail to give it its own full-bleed photo, or tag it Sides / Corners / Inside / Extra to combine every shot with that tag into one photo — e.g. tag all four corner close-ups Corners to combine them into one image, however you arrange them. Any leftover untagged photos are grouped into sets of 4 (2×2 grid or a row of 4) in the order you arrange them.
