Use a staging product with several photos, a variation selector and a zoom control.
Choose a demanding real product
Use a staging product with several photos, a variation selector and a zoom control. Record the expected images and option behavior. A single-image sample product will not exercise the gallery paths that customers use. Keep a baseline screenshot at a narrow viewport and note which picture appears first.
Inspect each interaction
Open the gallery, move to another photo, use zoom and select a variation. Confirm that the displayed image matches the option. Record when a new image becomes visible and whether the surrounding content moves. If the gallery works after a reload but not on first arrival, preserve both reproduction paths.
Separate delivery from functionality
WooCommerce’s extension guidance treats frontend performance as an implementation concern. In your audit, distinguish a large image transfer from a control that waits on JavaScript. Send the network trace for a delivery problem and precise interaction steps for a functional problem. Changing image quality does not repair a broken variation handler.
Trial the targeted change
On staging, adjust only the setting supported by your gallery or optimization component. Recheck product text and fine details at zoom. Check both the first picture and later pictures. Avoid processing the entire catalog until you know how originals, generated sizes and gallery markup are handled.
Use a catalog sample
Repeat with a simple product and another variation-heavy product. Keep a record of the selected resource, expected image and control behavior. Publish the change only when the representative journeys remain correct. This checklist supports a focused investigation; it is not a compatibility certification for every gallery extension.
