how to read images one by one from folder for operation using for loop

I have dataset of natural images. And my task is to add some noise in all image and then denoise them. I cant' rename that 5600 image manually. Will anybody please tell me how to use for loop to read each image one by one from the folder without modifying name of images.

I like to use the multiselect function of uigetfile as an input to a for loop:

[Names,Paths]=uigetfile({'*.img*'},'MultiSelect','on');  %or whatever file extension your images have
entirefile=fullfile(Paths,Names);

for i=1:numel(entirefile)  %loop will run a number of times equal to the number of files you selected
    %load your image using whichever function you prefer, by 
    %calling e.g. load(entirefile{i}) (note curly brackets)
    
    %a good way to keep your workspace clean while retaining all images loaded is to load them into a structure, e.g.
    imgstruc(i).raw=yourrawimage;
    imgstruc(i).noised=addsomenoise
    %and so on. 
end
