you will have to add a display to show images. after you have done so it should show an interface where you can select the topic. after selecting the right topic it should show a window, in which your image should be shown. the link provide by lakshmen contains a clear explanation how to do this.

He can't use the comment tool, he doesn't have enough karma.

Oh, man. I was wondering why so many people had been using answers to comment. I wonder if the admins would be willing to drop that rule.

Requiring karma is an antispam measure. You can always edit your own question though.

I can select the topic that publish my node, but I cant see any image. I can see this on rviz Displays: Global Options -> Fixed Frame: /camera. Global satatus: No tf data. Actual error: Fixed Frame [/camera] does not exist. Camera status: warning -> CameraInfo: No CameraInfo received on [/camera_info]; Image: No image image received

like i said in my answer, you will need to add a display of the type: "Image" (see this link: http://www.ros.org/wiki/rviz/UserGuide). in that display you have to add the topic. fixed frame is something completely different.(see the same link for an explanation of fixed frame)
