Displaying images side by side with imshow

Hi everyone ! I'm a student in civil engineering and this semester I have to work on Matlab with images and I'm unfortunately not that comfortable with images. here is my question : I have a camera that take (during one run) 33 fotos. It saved those 33 fotos (called "Image1.jpg", "Image2.jpg" ... "Image33.jpg") In a folder named "run". By using imshow, I manage to plot these 33 photos one next to the other (which is what I want). Here is my code :

    clear all;
    close all;
    for i=1:33,         %Insert the number of images that are in the "run" folder
        name = sprintf('Image%d.jpg',i);
        B{i} = imread(name);        % It reads the foto i 
        I{i} = rot90(B{i},3);       % Rotates each Image of the folder by 3*90 degree counterclockwise
    end
A = imshow([I{1} I{2} I{3} I{4} I{5} I{6} I{7} I{8} I{9} I{10} I{11} I{12} I{13} I{14} I{15} I{16} I{17} I{18} I{19} I{20} I{21} I{22} I{23} I{24} I{25} I{26} I{27} I{27} I{28} I{29} I{30} I{31} I{32} I{33}]);

My questions are :

1. Is there a way to display those images in a more beautiful way than the one I used : A = imshow ([I{1} I{2}...]), because if suddenly we have 40 fotos, we have to re-write the code manually.

2. To run this code, we have to be in the folder named run, where all the 33 fotos are placed. Let's imagine now that I have j folders named ¨run1¨, ¨run2¨ ...¨runj¨ and each folders contains let's say 33 fotos. The goal is to do the exact same manipulation with each folder, how can I do a loop to do that ?

Thank you very much for your answers, I hope my question is understandable, if not don't hesitate to ask me to clarify it.

folder='yourfolder' 
A=[];
for i=1:33,         %Insert the number of images that are in the "run" folder
  name = sprintf('Image%d.jpg',i);
  namef=fullfile(folder,name);
  B{i} = imread(namef);        % It reads the foto i
  I{i} = rot90(B{i},3);       % Rotates each Image of the folder by 3*90 degree counterclockwise
  A=[A I{i}];
end
imshow(A)

Thank you very much ! I'll try it this week when I go back to the lab. But already thank you for the quick answer !

Thanks you ! It worked perfectly ! :)

Hello and Happy New Year,

I would like to ask you, how can I display the same photos, that Damien Sommer said, in a 10x7 matrix and not in a row.

Thank you very much
