Randomly shuffle folder of images and save it

I have 5 images named 1.jpg, 2.jpg ... 5.jpg

I wanted to create a random number of 1 to 5 and write these images in the random number order, as 6.jpg, 7.jpg ... 10.jpg

Suppose the random order generated is 3, 1, 4, 5, 2

I wanted to write 3.jpg as 6.jpg; 1.jpg as 7.jpg; ..... 2.jpg as 10.jpg

Now i have total 10 images. Again I want to create a random number of 1 to 10 and write these images in the random number order, as 11.jpg, 12.jpg ... 20.jpg

Till I get 25 images in total in the folder

imgFiles = dir('*.jpg') ; 
N = length(imgFiles) ; 
n = randsample(1:10,N) ;  % you can out your limits here 
for i = N
    I = imread(imgFiles(i).name) ;
    fname = strcat(num2str(n(i)),'.jpg') ; 
    imwrite(I,fname) ;     
end
