By default Magento 2 creates more than 20 duplicates of each product image..! (why???)
I have got this down to 5 using view.xml in my theme, but there is one extra set of image sizes I need to change, these are set in
They are: product_listing_thumbnail, product_listing_thumbnail_preview, product_thumbnail_image.
I want to update it using my custom module. I have it at this path
But this is wrong. Is there a correct path that will work? (If creating an admin theme is the only way then I guess I could do that, but seems overkill for just one small change).
(Have spent ages looking online and through docs but can only find info for frontend view.xml, which I am already using, and putting the image names in this file does not work).
