Overview & Solution
You will see this error if Trade Me detect that you are using one image on two listings on Trade Me.
To fix you can change the images on the products in your eCommerce Store so they are not using the same image or have the same image URL.
Once you make this change you will need to do an import from Omnivore so that we can import the changes.
Alternatively you can exclude the image/s in Omnivore so that we will not send that image to Trade Me.
To exclude / block images in Omnivore please follow this FAQ Here.
