Overview

Amazon issues Error 100590 when a listing’s variant images are missing for a specific marketplace. The error does not suppress the ASIN, but the absent images are hidden from shoppers, potentially hurting conversion. Sellers need to locate the gap, upload compliant images, and verify marketplace standards to keep listings fully visual.

Key Points

• No ASIN suppression — The listing remains searchable and purchasable, but the error is flagged as non‑critical.
• Images stay hidden — Variant photos that trigger the error are not shown on the detail page, reducing visual appeal for those options.
• Variant‑specific trigger — The problem appears only when a particular size, color, or style lacks an image in the targeted marketplace.
• Fix is optional but advised — Amazon does not require immediate action, yet completing the image set is strongly recommended for better sales performance.
• Marketplace‑dependent standards — Image dimensions, background color, and file format may differ between Amazon stores, so an image valid in one region can still cause the error elsewhere.

How to Resolve Error 100590

1. Pull the processing report — Open the Feed Processing Summary for the recent upload; the report lists each ASIN, the variant SKU, and the exact image attribute flagged as missing. For example, the report may show “B07XYZ123 – Red‑Medium – MainImage – Missing.”
2. Cross‑check the variation theme — Review the product’s variation theme (e.g., Color‑Size) in the catalog and confirm that every defined attribute has a dedicated image entry. If the shirt line includes Red, Blue, and Green, each color must have at least one main image uploaded.
3. Prepare marketplace‑compliant files — Resize or re‑format the missing images to meet the target store’s guidelines (minimum 1000 px on the longest side, JPEG or PNG, pure white background for main images). A 1200 × 1200 px JPEG of the Green‑Medium shirt with a white backdrop satisfies both US and EU requirements.
4. — Use the “Add Images” function in Seller Central or include the corrected image URLs in a flat‑file feed, ensuring the SKU matches the variant identified in step 1.
