rviz camera display, camera_info problem [closed]

edit

My problem is that when I subscribe /usb_cam_repub/image_raw (republished usb_cam topic) in rviz, the rviz is finding /usb_cam_repub/camera_info by default, however, there is no topic.

I'm using Camera topic viewer in rviz (not image view). It displays frame coordinate on image, which is from other topic.

So I changed it once to /usb_cam, then camera_info is loaded in rviz once, then I changed to /usb_cam_repub, it will work.

In this case, how can I make rviz to use /usb_cam/camera_info with /usb_cam_repub/camera_info?
