No image output from /rgb topic

[Liu-Jinxin]

Hi, thanks for your magnificent work. I followed your guidance, but I found I can`t get the /rgb image. Is there anything to add to see the /rgb topic.

Thanks for your help in advance.

Regards,
Jinxin

@Liu-Jinxin, I'll create a docker environment to test everything. Should be much easier to play with the code.
