I would like to add a background image to the product images in Dawn theme, to replace the colour background.
Can anyone help?
Do you mean the on the product page as a whole here? If you could share a link to the page or a screenshot that would be much appreciated to know exactly what you mean.
Because this is a Shopify developed theme, our theme support team might be able to help you making this change if it's possible. If you're on a paid plan then you would also be eligible for 60 minutes of free design time which you could use to make this change. If you want to go this route, don't hesitate to contact and log in to talk to our support team here.
I mean the individual product image area, e.g. behind the main image as per the area that is coloured white for the second product.
This is currently set to the background colour, but I would like a background image to appear here.
Thanks for sharing and yep, the best way forward for you here would be to contact our support team and ask one of our advisors who can forward this to our theme support team to use the 60 minutes of free design for you.
