Here my codes:-
%Save the folder of images in the current directory
path_directory='/home/motmot/Documents/Malignant/M1/Testing/benign/validate_image/b245'; % 'Folder name'
original_files=dir([path_directory '/*.jpg']);
for k=1:length(original_files)
filename=[path_directory '/' original_files(k).name];
image_orginal=imread(filename);
img=im2double(image_original);
[r,c,b]=size(img);
data=reshape(img,r*c,b);
[ctr, class]=fcm(data,2);
disp(ctr);
class1=reshape(class(2,:),r,c);
imshow(class1);
imwrite(class1,'fcmgrayb245_73_864_rap00001.jpg');
end

If the images are not showing, except for the last one. Put a drawnow right after you call imshow.
imshow(class1);
drawnow;
This will force the images to update on the screen immediately. Otherwise if your loop is too fast, maybe only the last one is shown.

Maybe you want to create the file name dynamically:
...
outFile = fullfile(path_directory, sprintf('fcmgrayb245_73_864_rap%05d.jpg', k));
imwrite(class1, outFile);

Ok thanks. But I want to ask, about this code:-
outFile = fullfile(path_directory, sprintf('fcmgrayb245_73_864_rap%05d.jpg', k));
what is mean by the '%05d' from the last code? Is it 5 times repeating save the image?

See: doc sprintf, or sprintf
The %05d appears in the sprintf command. Then it influences the output to a char vector and not the number of times of saving. Try this:
sprintf('%05d', 17)
ans = '00017'
sprintf('%5d', 17)
ans = ' 17'
sprintf('%d', 17)
ans = '17'
The %5d reserves 5 characters. With %05d the leading characters are filled by zeros.
"fcmgrayb245_73_864_rap00001.jpg" looked like you want to append a counter at the end of the file name.
