client and server issue

[khaledgabr77]

I'm trying to publish a compressed image from a client and uncompressed it over the server.
i tried publishing the image_raw to the server and it's working normally. and this the line i was publishing the topic let img = "http://"+this.robos_ip[i]+":8081/stream?topic=/"+ this.robos_name[i] +"/rgb_camera/image_raw";
i change the web_video_server parameter default_transport=compressed and tried to publish a compressed image by using this line let img = "<http://"+this.robos_ip[i]+":8081/stream?topic=/"+> this.robos_name[i] +"/rgb_camera/image_raw&type=ros_compressed"; but i can't get any images.
when i use the last line this will publish a compressed images? or it will compressed the image then will uncompressed to image_raw?
