I have an image file of several hundred images and I need to sample and save 70 of these images without replacement and save them for use later in the experiment. How do I go about doing this?

% select 70 random indices without replacement between 1 and numImages
imIDX = randperm(numImages, 70) ;
for K = imIDX
% process image K
end
