Right now our theme is setup to show the 2nd pic at hover on the collection page. On mobile it is with a swipe. My client wants to show the 3rd pic on swipe on mobile. Possible? We are using the Elessi theme.
It can be but need to edit code of your theme.
This is Richard from PageFly - Shopify Page Builder App, I’d like to suggest this idea:
Regarding this issue, you should contact the theme to receive the necessary support or you must add custom code if in case your theme does not support that function.
Hope you find my answer helpful!
