If you have Computer Vision Toolbox you can use imageset().

If you don't have that toolbox something like this would work:

for i=1:10
  imList{i}=imread(strcat('J:\multimedia\photo\',file_name(i).name));
end

By the way, you better pass some image extension (when using dir), otherwise, you have to first check if what is in file_name is indeed an image before trying to reading it. You can use try/catch for that too.

MATLAB: How to retrieve multiple images from a database

You can do this easily..... before doing this program, you have to keep all of your image in a folder and rename them by any common char+number concatenation form (like a1.jpg, a2.jpg,a3.jpg....). after that you just use strcat() function for reading the path name, and then read the images.

%%%%%%%%%%%%%%%%%%%%%
for i=1:10 %suppose there are 10 image
  im=imread(strcat('J:\multimedia\photo\a',strcat(i),'.jpg'));
  imtool(im); 
end

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %the below code is for different image name

 folder_name=dir(strcat('J:\multimedia\photo\')); % the path tht u hv imges
  no_of_content=size(folder_name); 
  no_of_images=no_of_content(1,1)-3;
  for i=1:no_of_images 
    im=imread(strcat('J:\multimedia\photo\',folder_name(i+3).name));
    imtool(im);
  end
