imgur is a popular image sharing platform that can serve as an image CDN as well. imgur relies on OAuth 2 flow for authorizing requests to its API. Once clicking on authorize, you will be redirected to imgur to login and authorize imager200 to upload images on your behalf:

google auth

Once authorized, you can configure optional image metadata like the image title and the image description

google auth

Because the title and the description are not static and should normally be different from an image to another you can use the following headers to set them on a per request basis.

If set, the headers value has precedence over the configured ones.
