The binary which was sent to the MQTT server was not the binary but the string format of binary. Meanwhile, the binary format is correct if we used the command which was provided by mosquitto using the below command, for example mosquitto_pub.exe -h 192.168.80.196 -p 1884 -f C:\temp\1.png -t test1

Locate the Eclipse Paho MQTT Utility's file-publishing path and UI described by pahotoolbug.png and EclipseClientMockup.png. Compare its handling of image bytes with the raw bytes sent by the documented mosquitto_pub command; done means the utility provides the proposed raw-versus-HEX choice and publishes a selected image with the intended bytes.
