ROS: Display sensor_msgs/Image image form a custom topic

I have a problem with debugging my ROS code. I can't display an image to verify proper tracking.

Is there an easy way to display images from a custom message using a terminal, or do I have to write a new node that will display the image?

My message:

std_msgs/Header header
uint64[] object_ids
uint16[] class_ids
float32[] confs
int16[] x_coords
int16[] y_coords
int16[] bb_width
int16[] bb_hight
sensor_msgs/Image source_image

I want to display source_image coming from a topic /tracker_topic.

I tried using topic_tools relay_field, but I'm using python 3 which doesn't use Unicode, and I'm getting errors because of that.
