creating a loop to input photos into the code

I am very new to Matlab. I am trying to create a loop to input photos in, so I do not have to put in imread in 100 times. The file all the photos are in is called "Pathtoimages". I am trying to upload photos to have the machine recongizie and classify if a photo is a pengiun or a dog. I am not sure how to set this up. Any Help would be greatly appreiated . this is what I found on the internet but I do not understand sprintf or the "pentan1h_6uLmin_0%3d.tif" ( how do you create a file like that or is there a way to do it with a .m file?) . Any help would be greatly appreciated. Thank you.

for n=1:10
    images{n}= imread(sprintf('pentan1h_6uLmin_0%3d.tif',n));
    imshow(Images{n},[],'initialmagnification','fit');
end

hello

this code example reads all tif files in the current directory

the for loop will open each individual file and do a few operations (like cropping here)

it's up to you to adapt it to your specific needs....

% select appropriate options below and adapt code to your specific needs ...

% files = dir('*.tif');      % list all tif files in current directory
files = dir('handheld*.tif');      % as example : only list tiff files with "handheld" in the filename

% % resize options (sacle factor or pixels)
% scale_factor = 0.5;

% select portion of the image
% 451*279*3. I will like to extract a portion with dimensions of 120*80*3
x_dim = 120;
y_dim = 80;
x_offset = 100; % please make sure the "corner" of the cropped image is correct
y_offset = 50;

% main loop
for ck = 1:length(files)
    Filename = files(ck).name;
    img = imread(Filename);
    
%     % resize
%     H{ck}= imresize(img, scale_factor);

    % select (crop)
    H{ck}= img(x_offset+(1:x_dim),y_offset+(1:y_dim),: );

    % plot (just to check)
    figure(ck), imagesc(H{ck});
    
    % insert your own code here (save for example)
    
end
