Returning multiple images in one ResponseEntity body

I'm using spring boot to save some images to the db along with an order. I am able to return a single image at a time but I would like to return 2 or more images in the body. I tried using arrays or arrayLists but that didn't work. Is there a way to return multiple images ?

My code

    @GetMapping(value = "/getOrder")
    public ResponseEntity getOrder(@RequestParam Long input_id) {
        try {
            Optional<OrderItems> orderItemOptional = materialService.getOrder(input_id);

            if (!orderItemOptional.isEmpty()) {

                byte[] imageBytes = orderItemOptional.get().getEyewearImage().getImage();

                return ResponseEntity.ok().contentType(MediaType.IMAGE_JPEG).body(imageBytes);

            } else {
                return ResponseEntity.badRequest().body("Bad request");
            }

        } catch (Exception e) {
            LOGGER.warn(e.getMessage(), e);
            return ResponseEntity.badRequest().body(e.getMessage());
        }
    }
