Publishing images to http in ROS

If we want to view the image only, we could do it in a web browser. In ROS, there is a package named web_video_server as mentioned here, that achieves this. After the image is published, we have to rosrun web_video_server, and following the wiki, we only need to copy this in the browser: http://localhost:8080/stream_viewer?topic={ROS_TOPIC}.

For instance, if the topic is called /camera/image_color, then the address should be http://localhost:8080/stream_viewer?topic=camera/image_color, and we can see the image in the browser.
