The steps I explained to you through screenshots have been followed exactly by you.
Topic summary
Issue: In the Impulse theme, the secondary product image does not appear on hover in collection grids after some CSS changes. The merchant tried editing theme.css.liquid but couldn’t get the hover swap to work on a non-live store.
Guidance provided: A community member shared step-by-step screenshots on enabling/implementing the hover image behavior. The merchant followed the steps, but the secondary image still didn’t display, as shown in their screenshots.
Escalation: A supporter requested the store URL and password to inspect directly. The merchant shared multiple screenshots, noted the problem also affects the “collection-sierlijsten” collection, and appeared to provide preview access credentials. They also mentioned adding custom code with ChatGPT and were unsure if it’s correct.
Context/terms: “Secondary image on hover” = swapping to another product image when the user hovers a product card in the collection page. Changes were attempted in theme.css.liquid (theme stylesheet). Images and screenshots are central to understanding the setup.
Status/outcome: No confirmed fix yet. Further investigation is pending after access was shared; the thread remains open with unresolved root cause.
