Preview and QA a Product Image Experiment

Pre-launch checklist for product image experiments in Elevate A/B Testing, covering image quality, gallery behaviour, and where else product images appear.

---

Work through this in Preview, before launching. Images are the most visible thing on a product page, so a broken variation is obvious to visitors and expensive.

Image check

Check	What passes
Correct images assigned	Each variation shows the images you intended, on the products you intended
Quality	Nothing blurry, pixelated, or stretched
Cropping	Nothing important cut off, on any aspect ratio your theme uses
Consistency with the control	Dimensions, background, and framing match unless the difference is the thing you are testing
Order is correct	The intended image is the Default Image, and the rest follow in the order you set

If you generated images with AI, look at them properly rather than glancing. The product has to be recognisably as what the customer receives.

Gallery check

Check	What passes
Mobile gallery	Swipe through every image on a phone. Most image experiments matter most here.
Desktop gallery	Click through thumbnails and confirm each loads
Zoom	If your theme zooms on hover or tap, it works on the variation images
Variant switching	If images are tied to product variants, selecting a variant still shows the right image

Variant linked images are the most common failure. If your theme swaps the gallery when a colour is selected, check that behavior on every variation.

Scope check

Check	What passes
Right products	The experiment runs on the products you selected and no others
Across the set	If you selected many products, check several of them, not just the first
Elsewhere on the site	Check whether the first image also appears on collection pages, search, and cart, and whether it changed there too

That last one matters for interpretation. If the variation image appears on the collection page, the experiment is also testing the thumbnail that gets someone to the product page in the first place.

Tracking check

Check	What passes
Events are arriving	Viewing a tested product page produces an event
Correct variation recorded	The event records the images you actually saw
Add to cart is recorded	Adding the product produces a corresponding event
