I have three folders with 12 image in each folder. to comapre them i need to dispaly all the images across their coresponding predicted and ground truth image. Row 1 consists of 12 original images, Row 2 consists of 12 groung truth iamges and Row 3 consists 12 predicted images.

images = imageDatastore('D:\original images');
GroundT = imageDatastore('D:\ground truth'); 
Predict = imageDatastore('D:\ predicted'); 
for i = 1:12
    subplot(3,12,i)
    imshow(images.Files{i})
    hold on
    for j=13:24
        subplot(3,12,j)
        imshow(GroundT.Files{i})
        hold on
        for k=25:36
            subplot(3,12,k)
            imshow(Predict.Files{i})
        end
    end   
end

images = imageDatastore('D:\original images');
GroundT = imageDatastore('D:\ground truth'); 
Predict = imageDatastore('D:\ predicted'); 
for i = 1:12
    subplot(3,12,i*3-2)

Thank you for your answer but I need all the images in Row 1, all the groundtruth images in Row 2 and all the coresponding predicted images in Row 3.
