 * Set `"upscaler"` to `"None"` and `"scale"` to `1` if you don't need to upscale;

-* `"result_file_path"` is set to the `"outputs/api"` folder by default (please, create the folder beforehand to avoid any errors) with a timestamped filename; (output_YYYY-MM-DD_hh-mm-ss), you can set any specific path, e.g. `"C:/stable-diffusion-webui/outputs/api/output.png"`.

+* Set `"random_image"` to `1` if want ReActor to choose a random image from the path of `"source_folder"`;
+* Set `"upscale_force"` to `1` if you want ReActor to upscale the image even if no face found.
