Hello Kartik,
sensor_msgs/Image is a type of ROS message that contains variable sized sub-message fields.
As shown in the Modify maximum Size of Variable-length Array section of that example, you need to set the correct array-size of the "Data" message field for "sensor_msgs/Image".
Following snapshot of the Simulink model shows this setup.
Let us know if this answers your questions.
