You should create the Mat that contains both images (maybe using push_back)

^^ i think, poster means: 1 image on the same window as the rest of the gui (not in an external window)

What you can do is to create a Mat that contains both images you want to display and then give this Mat to the function that transforms it to MFC format

You should use the same name of the window in imshow function. Something like:

for (std::size_t i = 0, i < imgsPaths.size(); i++) // if you have a vector of images' paths
  cv::Mat img = cv::imread(imgsPaths[i]);
  cv::imshow("same window", img);
  cv::waitKey(); // for seeing the displayed image until key pressed

I am not sure what you want, so I am adding also another thing: If you want to display two images in the same window, you can do something like:

cv::Mat img1 = cv::imread("../img1.png");
cv::Mat img2 = cv::imread("../img2.png");
cv::Mat img3;
cv::imshow("img3", img3);

Or if you want to display them one next to each other, then you'll need to play a little more (like create a zero Mat of Size(width1 + width2, max(height1, height2)) and just copy the images in the specific places)

Nice the pushing of multiple mats in a vector was something I didn't know yet. Mostly I copy them to the desired region.

I think it is more correct if you display them in the region where you want, but this works for images with the same number of columns
