+Changelog Notes
+===============
+
+Jazzy Jalisco
+-------------
+There are several major change between ``Iron`` and ``Jazzy``:
+
+ * All components now properly support ``image_transport`` parameter.
+ * All components now properly support remapping the ``camera_info`` topic
+   for an associated ``image`` topic. For instance, if you remap ``image``
+   to ``my/image`` then ``my/camera_info`` will be used. Previously you
+   would have to manually remap the ``camera_info`` topic.

+
+``image_publisher`` provides a node/component for publishing images
+as a ROS 2 image topic.
+
+Simplest example is:
+

+Nodes and Components
+====================
+
+image_rotate::ImageRotateNode
+-----------------------------
+Node to rotate an image for visualization. The node takes a source
+vector and a target vector, and projects them onto the camera image.
+It then rotates the image by the angle neded to align the projection
+of the source vector with the projection of the target vector.
+The source and target vectors are specified in arbitrary TF
+frames allowing the rotation angle to vary dynamically as frames
+move relative to one another. With the default settings, the image
+will be rotated so that the top of the image matches the up
+direction the base_link.
+
+Subscribed Topics
+^^^^^^^^^^^^^^^^^
+ * **image** (sensor_msgs/Image): Image to be rotated.
+ * **camera_info** (sensor_msgs/CameraInfo): Camera metadata, only
+   used if ``use_camera_info`` is set to true.
+
+Published Topics
+^^^^^^^^^^^^^^^^
+ * **rotated/image** (sensor_msgs/Image): Rotated image.
+ * **out/camera_info** (sensor_msgs/CameraInfo): Camera metadata, with binning and
+   ROI fields adjusted to match output raw image.
+
+Parameters
+^^^^^^^^^^
+ * **target_frame_id** (str, default: base_link): Frame in which the target
+   vector is specified. Empty means the input frame.
+ * **target_x** (double, default: 0.0): X coordinate of the target vector.
+   Range: -10.0 to 10.0.
+ * **target_y** (double, default: 0.0): Y coordinate of the target vector.
+   Range: -10.0 to 10.0.
+ * **target_z** (double, default: 1.0): Z coordinate of the target vector,
+   Range: -10.0 to 10.0.
+ * **source_frame_id** (str, default: ""): Frame in which the source vector
+   is specified. Empty means the input frame.
+ * **source_x** (double, default: 0.0): X coordinate of the direction the
+   target should be aligned with. Range: -10.0 to 10.0.
+ * **source_y** (double, default: 0.0): Y coordinate of the direction the
+   target should be aligned with. Range: -10.0 to 10.0.
+ * **source_z** (double, default: 1.0): Z coordinate of the direction the
+   target should be aligned with. Range: -10.0 to 10.0.
+ * **input_frame_id** (str, default: ""): Frame to use for the original camera
+   image. Empty means that the frame in the image or camera_info should be
+   used depending on use_camera_info.
+ * **output_frame_id** (str, default: ""): Frame to publish for the image's
+   new orientation. Empty means add '_rotated' suffix to the image frame.
+ * **use_camera_info** (bool, default: True): Indicates that the camera_info
+   topic should be subscribed to to get the default input_frame_id.
+   Otherwise the frame from the image message will be used.
+ * **max_angular_rate** (double, default: 10.0): Limits the rate at which
+   the image can rotate (rad/s). Zero means no limit. Range: 0.0 to 100.0.
+ * **output_image_size** (double, default: 2.0): Size of the output image
+   as a function of the input image size. Can be varied continuously between
+   the following special settings:
+
+   * 0 ensures no black ever appears
+   * 1 is small image dimension
+   * 2 is large image dimension
+   * 3 is image diagonal
