How to Enable Image Zoom and Rollover in Shopify Warehouse Theme

Warehouse supports two related but different product-image features: zoom (inspect a photo up close) and rollover (hovering a thumbnail swaps in a second image), both useful for a catalog where shoppers compare similar-looking items.

Steps

1. In your Shopify admin, go to Online Store > Themes and click Customize on Warehouse.
2. Open a product page and select the Product images or Media block.
3. Turn on the zoom setting and choose click or hover as the trigger.
4. Turn on the rollover setting — this needs a second image assigned to that variant or product to have something to swap to on hover.
5. Click Save.

Rollover matters more on Warehouse than on most themes — for technical or industrial products, showing a second angle (a back panel, a connector, a size reference) on hover helps shoppers self-serve details without opening the full gallery.
