Amazon main images usually need a clean product view, and screenshots or lifestyle photos often fail marketplace review.
Replace main images with product-only files on a white background, then rerun the batch report.
Low-resolution supplier images may pass a quick visual review but fail the pixel requirements needed for marketplace zoom.
Use the report to identify short-edge failures and request or export larger originals before uploading.
Marketplace upload flows can reject unexpected formats, spaces, or names that do not match SKU handoff rules.
Convert files to the accepted format and rename them consistently before packaging the final image set.
