There is an /Update Image /API, documented at https://docs.openstack.org/api-ref/image/v2/index.html?expanded=update-image.... It does require an HTTP request body in JSON format.
However, it updates the /image catalog entry, /not the image data. If you want to replace image data, this is not possible, since the image catalog entry contains a checksum that can't be modified. Modified image data would not correspond to the checksum anymore (see the second note under https://docs.openstack.org/api-ref/image/v2, which also states "images are immutable").
