I'm not able to post the image files...how to do it?

please use online sharing site for sharing the images... you may use dropbox.com

could you set the background to black and add Grid in the rviz for the pointcloud image and send the screenshot again

please add tf also to the rviz so that the tf frames are seen in the display

I'm not able to launch openni i'm getting error as
