Shopify collection cover images: find missing images and ratio mismatches
Collection cover images can have different source dimensions and still appear acceptable in a theme. Audit the source data, then check the actual storefront design before changing assets.
Five steps for a reviewable collection audit
A themed collection grid may crop or letterbox cover images. Source images with unusual aspect ratios can create extra editing work, especially before a sale or storefront refresh.
Inventory collections used in navigation, campaign pages and collection grids. A missing image is not always a problem, but it should be a deliberate choice.
Review image width and height and compare aspect ratios across the group. Note outliers rather than treating every difference as an error.
Preview the actual Shopify theme on desktop and mobile. Theme image containers and cropping settings determine the customer-facing result.
Export collection links and image findings for the content team. Prioritize visible defects and high-traffic collections, then choose approved replacements.
Once the merchant has updated image assets separately, run another audit and inspect the storefront on real devices.
PAL Collection Ratio Guard
PAL Collection Ratio Guard checks whether collection cover images are present, reports source image dimensions and aspect ratios, flags ratio mismatches for review, and exports a CSV. It does not modify collection images.
Scope and limitations: A flagged ratio is a review signal, not proof of a broken storefront. The app does not crop, resize or replace images automatically.

Should every Shopify collection image use the same aspect ratio?
Not always. Match your design system and theme behavior. Review outliers visually before making changes.
Will this tool resize images?
No. The app provides read-only diagnostics and a CSV worklist. Image changes remain under merchant control.
What should I check after an image update?
Preview relevant collection cards on desktop and mobile and repeat the source-image audit.
