I'm not sure what you are trying to do. If it is "display the image", a google search "display image ros" returns this page as first link https://wiki.ros.org/image_view

From that page:

rosrun image_view image_view image:=<image topic>

So if you want to see the raw image coming out of your camera you can do

rosrun image_view image_view image:=/image_raw

If this is not what you are trying to do, please edit your question providing more details

HTH,
