Amazon keeps rejecting your new photos? Check the size data on the listing first
Amazon rejecting your new product photos after a pack change? The cause is often stale size data on the listing. Here is what to check, and in what order.
You changed the pack size, shot clean new photos and uploaded them. Amazon refused them, or accepted them and kept showing the old picture. So you re-crop, re-shoot and upload again. With new packaging going live before Black Friday, every week the old photo stays up is a week shoppers see a product you no longer ship. In our experience, the photo is often fine. The problem sits in the listing's size data, which still describes the old product.
What the error says, and what it usually means
Amazon has technical and content rules for product images. Images that miss them can be rejected, removed or altered, and non-compliant images can get a listing suppressed, which means pulled from search results. Amazon also states that uploading an image does not guarantee it will be displayed.
The message we see most after a pack change reads like a photo problem. It says the main image (the first photo on the page, and the one shown in search) does not accurately represent the product, or that the product identifier you submitted is incorrect. In our experience it often carries error code 100560. The second half of that sentence is the clue. Amazon is telling you the photo and the listing disagree. It does not say which one is wrong.
Two places to look first in Seller Central, Amazon's seller dashboard: the Fix your products page, which lists products removed from search for image issues, and the Submission status page, which shows images that failed compliance or file checks.
How your photo gets checked against the catalogue record
Every product on Amazon has an ASIN (Amazon Standard Identification Number), and every ASIN has a catalogue record: title, brand and attributes such as unit count, volume, weight and item form (liquid, cream, bar). From what we see on the accounts we run, Amazon reads a new photo against that record. If the record says one size and the label in your photo says another, the photo loses.
Illustrative example: the listing still says 250 mL, 1 count, and your new photo shows a 400 mL bottle with the new size printed on the front. You can re-crop that image twenty times. It will keep failing until the record says 400 mL.
This happens most when a brand resizes or rebrands and keeps the same UPC (the barcode number). A matching UPC tells you the listing is attached to your product. It tells you nothing about whether the size data is current.
A Canadian detail: units are entered differently on the two marketplaces. In our experience with beauty listings, Amazon.ca accepted the unit count in millilitres while Amazon.com would only take fluid ounces. When you enter the imperial figure, copy it from the label instead of converting it yourself. A converted number that appears nowhere on the pack is one more mismatch.
Why reusing an old listing for a new size makes it worse
It is tempting to take an old ASIN, from a discontinued size or a product you stopped selling, and rewrite it for the new pack. It keeps the page and saves a step. Amazon's rules are clear: an ASIN must represent only one product, the same product in every store, and changing a detail page to a new product or version is a violation. Each size in a variation family (the group of sizes or scents shown on one page) gets its own ASIN.
There is also a practical cost, and selling in Canada makes it sharper. In our experience, the image check on an Amazon.ca listing can run against the ASIN's US or global record, which you may not be able to change from the Canadian side. We have seen a reused listing take a new title, new text and a place in the family, then hide every image because the US record still described a much larger, different product. The error appeared more than an hour after the listing looked clean. More uploads did not fix it.
The fixes that work are slower: a new ASIN on a barcode that matches the product in the photo, or a catalogue correction case opened in Seller Central. If you plan a new size for the holidays, budget time for a new ASIN from the start.
The order that works
Fix the data, let it settle, then send the image. On the accounts we run, this is the order that clears these errors. Reversing it mostly produces more rejections.
The swatch tile has its own picture
On a page with several sizes or scents, shoppers choose from small tiles called swatches. In our experience, some listings carry a separate swatch image, set on its own, and keep showing it after the main image changes. Listings without one simply reuse the main image. So you can push a perfect new main image and still have the old pack sitting in the size tile right under it. Shoppers notice when the tile and the photo don't match.
After any main image change, look at the tiles on the live page, on each marketplace, and re-point any swatch image that still shows the old pack. Do it the same day as the main image update, while you still have the files open.
When Amazon rejects new photos after a pack change, check the listing before you touch the photo. Compare the size on the label with the size on the record, fix the record, then resubmit a fresh file. Give every new size its own ASIN. Then check the swatch tiles before you call it done. It is a short list, and it can save weeks of re-shooting in the busiest quarter of the year.
