Hello, can you a minimal reproducible example with more information?
How big are your images? Can you lower their resolution? Maybe you should compress their resolution a bit (based on your needs, of course). Choice of C++over Python implementation of your subscriber node also can speed things up.
Perhaps you can also check zero-copy transfer (here: https://discourse.ros.org/t/using-zero-copy-transport-in-ros2-with-ros2-shm-msgs/26226).
This tutorial is for ROS1 Noetic and Raspberry Pi, but you can check some more general hints:
