It's required to add multiple or single images to multiple individual products, which will be visible in PLP and respective PDP, besides those images needs to be shown on PLP as thumbnail.
Any recommended approach to bulk upload and storage those medias, except adding images to code base in the target product catalog and creating media container and media and product link via impexes?
Based on the requirements, I would recommend using the CLOUD HOT FOLDER for bulk importing media as well as storing them.
This approach will allow you to efficiently manage and import your media files.
