I'm a photographer looking to organize a large personal image library, and I also build websites for clients that may need to serve thousands of images. I'd like to store the files along with details such as titles and other metadata, then retrieve both the images and their associated data through an API. Ideally, the solution should be easy to integrate, reasonably affordable, and scalable as a client's collection grows.

For a quick, low-maintenance solution, you could use a managed media platform or a content management system with an API. Just make sure it supports bulk uploads, metadata search, image resizing, access controls, and predictable pricing before committing.
If you already use a particular cloud platform, its native object storage is a solid choice—Amazon S3, Azure Blob Storage, or a similar service. Put the image files there and expose the metadata through your own API. A headless CMS such as Sanity can be useful when nontechnical users need to manage the images and descriptions.
A flexible cloud setup would be object storage such as Amazon S3 for the image files, plus a small API and a database such as DynamoDB for the metadata. Keep the actual images out of the database and store their paths or URLs alongside titles, tags, and other fields. That approach scales well and can stay inexpensive for large collections.
Cloudinary is probably the easiest all-in-one option. It handles image storage, metadata, transformations, delivery, and API access, so you don’t have to build as much infrastructure yourself.

You can also start with the storage service and a simple JSON metadata file for a smaller project, then move to a database once you need searching, filtering, or multiple users updating the catalog.
