bigcommerce image optimization
Test faster BigCommerce product images without rebuilding the storefront
Skymage helps BigCommerce teams validate right-sized product cards, category grids, PDP galleries, and mobile image variants from the current catalog media before changing theme code across the whole store.
BigCommerce image test:
1. Product card
?w=520&h=650&fit=cover&f=webp&q=82
2. PDP gallery
?w=1400&fit=contain&f=avif&q=85
3. Mobile category tile
?w=360&h=450&fit=cover&f=webp&q=80
storefront surfaces
BigCommerce image tests should start where products repeat
Collection pages, search results, PDP galleries, and merchandising blocks often reuse the same source product media. The first win is mapping the repeated image slot and serving the exact variant it needs.
PDP galleries
Keep product detail clear without shipping source-size catalog images to every gallery slot.
Search results
Use smaller cached variants for search cards, related products, and merchandising blocks.
Mobile storefronts
Cut transfer size for mobile browsing while keeping stable card dimensions.
first rollout
Test one BigCommerce page before changing the whole theme
