Would this be something tf2_ros::MessageFilter could be used for?

Would this also be a good way to synchronize images and CameraInfo messages?

As CameraInfo does have a Header, it could potentially be used, but ppl typically would use image_transport to match frames with their corresponding CameraInfo messages (via a CameraSubscriber).

See also answers.ros.org#290341.
