I am having an issue with products images in Magento 2. The products were brought in from a Magento 1.7 install using the data migration tool. I then copied the media/catalog folder from the M1 install to the M2 install.
It appears that everything is working correctly: the product images show up in the Admin tool, and all of the products have thumbnails in the category listings. But when I click through to the product page, Magento 2 loads the default placeholder.
Even when I upload a new image and set it as the base, it does not appear on the product detail page.
I ran find ./pub/media -type d -exec chmod 777 {} \;
and find ./pub/media/catalog -type f -exec chmod 777 {} \;
to make sure it wasn't a permission issue, but I still can't get the product image to load.
I'm not sure how to debug this further, since it loads a placeholder I can't see what it is trying to load instead of the proper image.
Why isn't my product image loading?
php bin/magento catalog:images:resize
