A practical guide for merchants, theme developers and support teams configuring zoom, Progressive Product Zoom, Sticky Cart and Gallery Page.

Watch image zoom, mobile interactions, Sticky Cart and Gallery Page working together in a real product journey.
The responsive default for desktop, tablet and mobile. It supports gallery navigation, touch gestures and product video.
An optional desktop-only flow: hover lens → product popup → second-click deep zoom. Target all products, a Shopify tag or selected product IDs.
Phones and tablets automatically use Smart Lightbox so tap, swipe and pinch remain predictable on touch screens.
Progressive Zoom availability follows the feature permissions configured for each plan in the app admin. Do not hard-code plan names in theme code.
Progressive Zoom can be published selectively without changing the mobile experience. Open Zoom Setup → Optional Progressive Product Zoom, enable it, then choose an Apply to rule.
Use the desktop progressive journey across the full catalog. Best when product images and product-page markup are consistent.
Enter one exact Shopify product tag, such as progressive-zoom. Add that tag to every product that should use Progressive Zoom.
Enter the Shopify numeric product IDs shown in the product admin URLs. Use this for a controlled collection of individual products.
Targeted products use Progressive Zoom only on supported desktop pointers. Mobile, tablet and non-targeted products continue using Smart Lightbox.
The master switch controls which image tools shoppers can use inside supported viewers. Enable only the tools that improve inspection for your catalog.
Turn off the master switch to remove transformation tools together. Available controls follow the current plan and viewer type.
Use these settings to keep the lightbox consistent with the storefront design while preserving clear, touch-friendly controls.
Keep strong contrast between icons and their backgrounds. Always preview toolbar alignment on both desktop and mobile before publishing.
Sticky Cart keeps the purchase action visible after the main product form scrolls out of view and follows the currently selected product state.
The Sticky Cart should use the store's normal cart flow. Test products with unavailable variants, sale prices and multiple options before publishing.
Create a visual discovery page with Shopify-hosted images, responsive layouts, lightbox viewing and optional product tags.
Keep important subjects away from image edges so responsive cropping does not hide product details. Feature availability follows the current plan.
The automatic media detector supports modern Online Store 2.0 themes. Customized product galleries may need a manual product-media selector.
Confirm the app embed is enabled on the published theme, Zoom Setup is enabled, the plan grants the selected feature and the product media is detectable.
Disable the theme's built-in zoom or lightbox, then retest in a private window.
Verify touch-action rules are not overridden by theme CSS and confirm the Smart Lightbox mobile fallback is enabled.
Confirm the settings request completed, the existing storefront configuration was published and cached assets have refreshed.
Send the store URL, theme name, product-page link and a short screen recording.
