### API
pict-rs offers four endpoints:
- `POST /image` for uploading an image. Uploaded content must be valid multipart/form-data with an
    image array located within the `images[]` key

    This endpoint returns the following JSON structure on success with a 201 Created status
    ```json
    {
        "files": [
            {
                "delete_token": "JFvFhqJA98",
                "file": "lkWZDRvugm.jpg"
            },
            {
                "delete_token": "kAYy9nk2WK",
                "file": "8qFS0QooAn.jpg"
            },
            {
                "delete_token": "OxRpM3sf0Y",
                "file": "1hJaYfGE01.jpg"
            }
        ],
        "msg": "ok"
    }
    ```
- `GET /image/download?url=...` Download an image from a remote server, returning the same JSON
    payload as the `POST` endpoint
- `GET /image/{file}` for getting a full-resolution image. `file` here is the `file` key from the
    `/image` endpoint's JSON
- `GET /image/{size}/{file}` where `size` is a positive integer. This endpoint is for accessing
    thumbnails from an uploaded image.
- `DELETE /image/{delete_token}/{file}` to delete a file, where `delete_token` and `file` are from
    the `/image` endpoint's JSON
