I bought something from Amazon that came malfunctioning in certain areas. I would like to upload a photo depicting this malfunction to the product's page to warn other users of this problem. I read Amazon's FAQ about how to upload photos, but they seem to be outdated.
The FAQ states:
To add product images to existing listings:
Go to the product detail page of the item you want to add an image to.
Click Share your own customer images from the main view, or Upload images when looking at existing customer images.
I did not see any of the aforementioned interface items on the product page.
