Hello
In a 2 * 2 mode, function subplot works well and the third and fourth places are assigned to the third image.
Example
subplot (2,2,1),imshow(pic1)
subplot (2,2,2),imshow(pic2)
subplot (2,2,[3,4]),imshow(pic3)');
But in a 4 * 5 mode, for example, I want a photo to be placed in places 3, 8, 13 , 18, what should I do ??
Thanks for your help

Try this:
% Put image into central column.
% Note: it will maintain the aspect ratio of the image
% and not be stretched vertically into a tall and skinny image.
subplot(4, 5, [3, 8, 13 , 18]);
imshow(pic);

Try this:
pic = imread('river.jpeg');
[rows, columns, numColors] = size(pic)
% Resize image to be 5 times as tall as it is wide
stretchFactor = 5;
pic = imresize(pic, [columns * stretchFactor, columns]);
for k = 1 : 20
subplot(4, 5, k);
text(0.5, 0.5, num2str(k));
end
% Put image into central column.
% Note: it will maintain the aspect ratio of the image
% and not be stretched vertically into a tall and skinny image.
subplot(4, 5, [3, 8, 13 , 18]);
imshow(pic);

The stretchFactor will vary depending on the shape and size of the figure so you might want to specify that in advance so that it looks the same on everyone else's computer.
