The rotating images behind the headline on the shop's front page. They change every 5 seconds and customers can swipe between them on a phone. Leave this empty and the site keeps its built-in stock images — it never shows a blank hero.
What works here
Landscape, at least 2000px wide. 2400 × 1350 is ideal.
Keep the subject centred. On a phone the image crops hard to the sides — anything near the left or right edge is cut off.
JPEG or PNG, under 5 MB each. They are resized and compressed automatically on upload.
No text in the picture — the headline sits on top of it.
They are darkened and slightly desaturated so white text stays readable, so a bright busy shot still works.
Up to 6. Two or three strong ones beat six weak ones.
