    """Plots a gallery of images with bounding boxes.

    This function can display both ground truth and predicted bounding boxes on
    a set of images.  It supports various bounding box formats and can include
    class labels and a legend.

    Args:
        images: A 4D tensor or NumPy array of images. Shape should be
            `(batch_size, height, width, channels)`.
        bounding_box_format: The format of the bounding boxes.
            Refer [keras-io](TODO)
        y_true: A dictionary containing the ground truth bounding boxes and
            labels. Should have the same structure as the `bounding_boxes`
            argument in `keras.visualization.draw_bounding_boxes`.
            Defaults to `None`.
        y_pred: A dictionary containing the predicted bounding boxes and labels.
            Should have the same structure as `y_true`. Defaults to `None`.
        value_range: A tuple specifying the value range of the images
            (e.g., `(0, 255)` or `(0, 1)`). Defaults to `(0, 255)`.
        true_color: A tuple of three integers representing the RGB color for the
            ground truth bounding boxes. Defaults to `(0, 188, 212)`.
        pred_color: A tuple of three integers representing the RGB color for the
            predicted bounding boxes. Defaults to `(255, 235, 59)`.
        line_thickness: The thickness of the bounding box lines. Defaults to 2.
        font_scale: The scale of the font used for labels. Defaults to 1.0.
        text_thickness: The thickness of the bounding box text. Defaults to
            `line_thickness`.
        class_mapping: A dictionary mapping class IDs to class names.  Used f
            or both ground truth and predicted boxes if `ground_truth_mapping`
            and `prediction_mapping` are not provided. Defaults to `None`.
        ground_truth_mapping:  A dictionary mapping class IDs to class names
            specifically for ground truth boxes. Overrides `class_mapping`
            for ground truth. Defaults to `None`.
        prediction_mapping: A dictionary mapping class IDs to class names
            specifically for predicted boxes. Overrides `class_mapping` for
            predictions. Defaults to `None`.
        legend: A boolean indicating whether to show a legend.
            Defaults to `False`.
        legend_handles: A list of matplotlib `Patch` objects to use for the
            legend. If this is provided, the `legend` argument will be ignored.
            Defaults to `None`.
        rows: The number of rows in the image gallery. Required if the images
            are not batched. Defaults to `None`.
        cols: The number of columns in the image gallery. Required if the images
            are not batched. Defaults to `None`.
        data_format: The image data format `"channels_last"` or
            `"channels_first"`. Defaults to the Keras backend data format.
        kwargs: Additional keyword arguments to be passed to
            `keras.visualization.plot_image_gallery`.

    Returns:
       The output of `keras.visualization.plot_image_gallery`.
