I think this is not possible within OpenCV: http://docs.opencv.org/modules/highgui/doc/user_interface.html?highlight=show#

You could try to manually copy the different images in a single cv::Mat and feed that to imshow

You can only do this one way in OpenCV and that is creating one giant cv::Mat that is composed of the three images and imshowing that matrix, this can be done like this:

cv::Size s1 = img1.size();
cv::Size s2 = img2.size();
cv::Size s3 = img3.size();

cv::Mat output(s1.height, s1.width + s2.width + s3.width, CV_MAT_TYPE); // put in the type of your mat

cv::Mat help1(output, cv::Rect(0,0, s1.width, s1.height);
cv::Mat help2(output, cv::Rect(s1.width, 0, s2.width, s2.height);
cv::Mat help3(output, cv::Rect(s1.width + s2.width, 0, s3.width, s3.height);

img1.copyTo(help1);
img2.copyTo(help2);
img3.copyTo(help3);

cv::imshow("Output", output);
