@rotating_image I'n not sure I follow. Assigning an image to a pointer doesn't seem right. – juanchopanza Sep 11 '12 at 05:47

#include "iostream"
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace std;
using namespace cv;

int main()
{
    Mat image = imread("C:\\lena.jpg");
    IplImage image2 = image;
    cvShowImage("TESTiplimage",&image2);
    imshow("TESTmat",image);
    waitKey(0);

    return 0;
}

...try this code it...it works for me...you should get 2 windows showing the same image..
