Scroll a two-up image gallery under a sticky buy box
Product images run as a two-column grid that scrolls while the buy box (colours, sizes, fit note, CTA) stays pinned beside it.

What it is
Instead of a carousel, the product images run as a two-column grid that the shopper scrolls through, while the buy box (price, colour swatches, size grid, a fit note and the add button) stays pinned on the right.
Why it works
A carousel hides most images behind clicks that few people make. A scrolling grid shows every angle at a natural pace, and pinning the buy box means the shopper can act at the exact moment an image convinces them, without scrolling back up.
How to test it
- Hypothesis
- Replacing the gallery carousel with a scrolling two-up grid beside a sticky buy box will lift desktop add-to-cart rate.
- Primary metric
- Add-to-cart rate (desktop product page sessions)
- Guardrail metric
- Page load time, since the grid loads more images up front
