How to rename all the images in the directory

I have a directory that contains 200 jpeg images. What I want is to rename all these images. So how can I rename all my images at the same time. for example I want to rename the first image to "hello1", "hello2" for the second, "hello3" for the third....>"hello200" for the 200.

Below you can find my code:

maximagesperdir = inf;
directory='imagess';
dnames = {directory};
fprintf('Reading images...');
cI = cell(1,1);
  c{1} = dir(dnames{1});
  if length(c{1})>0,
    if c{1}(1).name == '.',
      c{1} = c{1}(4:end);
    end
  end
  if length(c{1})>maximagesperdir,
    c{1} = c{1}(1:maximagesperdir);
  end
  cI{1} = cell(length(c{1}),1);
  for j = 1:length(c{1}),
    cI{1}{j} = double(imread([dnames{1} '/' c{1}(j).name]))./255;
  end
fprintf('done.\n');

If you're just looking to rename the files and not to perform an operation on the images and then rename, there's always the total commander program which is a useful little thing to have. You select all the files and by using ctrl+m you select the way by which you would like to rename them (date, name, etc). Very simple if you're looking to perform the renaming operation scarcely. I'm just saying...

Here is some code to rename all the files in the current directory, the code you showed appears to read and not rename.

fnames = dir('*.jpg');
for i = 1:length(fnames)
   old_name = fnames(i).name;
   new_name = sprintf('hello%d.jpg', i);
   movefile(old_name, new_name)
end
