Hello,

I have 40 sub folders each with 10 images per subfolder. Each pgm image is 112 x 92.

I wanted to generate 8 figures. Each figure should have 10 images per line (= 1 folder per line). Therefore, each figure will contain 5 folders, giving a total of 50 images per figure. How do I go about showing these images in this specific format?

Here is the code to extract the images:

faces=zeros(10304,total_number_images);
    for i=1:numFolders
        cd(strcat('s',num2str(i)));
        for j=1:number_images
            a=imread(strcat(num2str(j),'.pgm'));
            imshow(a);
            hold on
            faces(:,number_images*(i-1)+j)=a(:);
        end
        cd ..
    end
hold off

I have also attached the first folder of images.

Thanks for your time and help.
