Question

Photo hosting

it is necessary that the web application uses another service through the API for storing and constantly reading and writing data,

it must be cheap

Answer 1

Amazon S3 or equivalent.

Answer 2

starting from a certain volume, ready-made third-party services like amazon s3 become very expensive
, so you raise your vps-ku and on it your own service with your api (for some reason, people think that their s3 at minimum is difficult, in overwhelming cases it is several hours of work on average programmer)
google: self hosted s3 compatible storage software
