Upload image files to a Book.

You can upload a file to this endpoint as a multipart/form-data encoded payload. To learn more, see multipart/form-data guide.

With the capability to classify images, you can upload a single image using this endpoint. To upload multiple images to the same Book, call this endpoint once for each image, and then call the Finalize image group endpoint to complete the Image group.

We support uploads of the images in the JPEG, PNG, BMP, and TIFF (Single-image files only) formats.
