problem in displaying an image

edit

Hi, I want to publish 10 images from my pictures folder..so that I added the link for that..code runs correctly but image is not displaying..

pub.cpp:

#include <ros/ros.h>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <cv_bridge/cv_bridge.h>
#include <image_transport/image_transport.h>
#include <sensor_msgs/image_encodings.h>

int main(int argc, char** argv)
{
  ros::init(argc, argv, "image_publisher");
  ros::NodeHandle nh;

    cv_bridge::CvImage cv_image;
    cv_image.image = cv::imread("/home/abi/Pictures/attachments/",CV_LOAD_IMAGE_COLOR);
    cv_image.encoding = "bgr8";
    sensor_msgs::Image ros_image;
    cv_image.toImageMsg(ros_image);
 image_transport::ImageTransport it(nh);
  image_transport::Publisher pub = it.advertise("/static_image/compressed", 3);
  ros::Rate loop_rate(5);

  while (nh.ok()) 
  {
    pub.publish(ros_image);
    loop_rate.sleep();
  }
}

sub.cpp:

#include <ros/ros.h>
#include <image_transport/image_transport.h>
#include <opencv/cv.h>
#include <opencv/highgui.h>
#include <cv_bridge/cv_bridge.h>

void imageCallback(const sensor_msgs::ImageConstPtr& msg)
  {
    cv_bridge::CvImagePtr cv_ptr;
    try
      {
    cv_ptr = cv_bridge::toCvCopy(msg, "bgr8");
         //ROS_INFO("Hi");
        cv::imshow("view", cv_ptr->image);
        cvNamedWindow("view",CV_WINDOW_AUTOSIZE);
      }
    catch (cv_bridge::Exception& e)
      {
    ROS_ERROR("cv_bridge exception: %s", e.what());
    return;
      }
}

int main(int argc, char **argv)
{
  ros::init(argc, argv, "image_listener");
  ros::NodeHandle nh;
  cvNamedWindow("view",CV_WINDOW_AUTOSIZE);
    image_transport::ImageTransport it(nh);
  image_transport::Subscriber sub = it.subscribe("/static_image/", 1,imageCallback);
  ros::spin();
  cvDestroyWindow("view");
}
