Composite of multiple small images over a larger background image

Hello everyone,
Allow me to concisely set the scene for my question. I am currently running a bunch of simulations that result in ternary composition diagrams using MATLAB. For the sake of comprehensiveness of the dataset I am making composites of images overlayed over a background. To be exact, I am using one background for every figure and am than inserting 66 smaller figures on certain locations in the figure.
For an example you can check the attached figure. As you can see, the smaller images require to be at exact spots in the larger image.
The figures are all generated in MATLAB and then saved as .png using the export_fig function.
Currently I am doing this operation in Powerpoint but it takes a very long time to complete one figure and it is also very repetitive. I would thus like to know if it is possible do automate this process using matlab, i.e. overlaying multiple figures at specified locations over a background figure...
Regards
Dries

If you have coordinates of the triangles in hand, it can be automated with ease....Check the below code...when figure is prompted click twice to cover a triangle as to get a bounding box. Click the points as to make a square which covers whole triangle. That clicked area will be filled by the small image. You can further take care of transparency on reading the documentation of how to show .png files.
[I,map] = imread('big.png') ;
Is = imread('small.png') ;
figure
image(I)
hold on
for i = 1:10
[x,y] = ginput(2) ;
image([x(1) x(2)] ,[y(1) y(2)],Is) ;
end
If the coordinates are in hand, instead of clicking the point limits can be incorporated to automate.

Here's the official Mathworks instructions for sending pictures from MATLAB to Powerpoint: https://www.mathworks.com/matlabcentral/answers/103175-how-can-i-create-slides-in-ms-powerpoint-2007-using-matlab-7-13-r2011b. It uses ActiveX. With ActiveX you can do virtually anything from MATLAB that you could do in Powerpoint itself. For example, specifying where on the slide the image should be put.
If you still want to go with the pasting small images onto a larger image, like KSSV suggested, and then inserting only one picture within Powerpoint, then see my attached copy and paste demo.
