How can I download/upload images in a REST API?

Question

I'm about to code my first API for my codeigniter application (Using the popular REST library), but I couldn't find a way to let users upload and download my application's images through the API. How is it usually done in API's?

I appreciate your help. :)

Solution

API uploads or downloads are done the same way whether you have a web application or a web service. You must use a multipart/form-data in a POST request for uploads, and send the proper response headers in downloads. In short, the PHP manual on file uploads and say, readfile for downloads, still applies for APIs.

This is really impotent. Could you please give us an example code.
