saving series of image

 imwrite(imageArray,'C:\Users\Public\Videos\Sample Videos\pro\New','jpg');
this is my code to read series of image and save it to other directory
however i could not save it properly..
>>   for k = 2 : 10
% Get the base file name.
baseFileName = sprintf('img%d.jpg', k);
% Combine it with the folder to get the full filename.
fullFileName = fullfile(folder, baseFileName);
% Read the image file into an array.
imageArray = imread(fullFileName);
figure,imshow(imageArray);
imwrite(imageArray,'C:\Users\Public\Videos\Sample Videos\pro\New','jpg');
end

See the FAQ for proper code that you can modify to do that: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Really? Wow, that's very surprising. Did you have an error message? OK, I did it for you. See if you can modify this code:

% Define input and output folders.  CHANGE THESE!!!!
inputFolder = pwd;
outputFolder = 'D:\Temporary stuff';
% Check to see that they both exist.
if ~isdir(inputFolder)
  errorMessage = sprintf('Error: The following input folder does not exist:\n%s', inputFolder);
  uiwait(warndlg(errorMessage));
  return;
end
if ~isdir(outputFolder)
  errorMessage = sprintf('Error: The following output folder does not exist:\n%s', outputFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of files to copy.
filePattern = fullfile(inputFolder, '*.jpg');
fileNamesToTransfer = dir(filePattern);
numFiles = length(fileNamesToTransfer);
% Do the copying.
for k = 1 : numFiles
  % Get the base file name.
  baseFileName = fileNamesToTransfer(k).name;
  % Create the full input and output filenames.
  fullInputFileName = fullfile(inputFolder, baseFileName);
  fullOutputFileName = fullfile(outputFolder, baseFileName);
  fprintf(1, 'Now copying file #%d of %d: %s to %s\n', ...
    k, numFiles, fullInputFileName, fullOutputFileName);
  copyfile(fullInputFileName, fullOutputFileName);
end
msgbox('Done copy files!', 'modal');

there is furter modification in the code..m still finding myself unable to save the images..pls look to my new code

Rohan, you totally ignored the FAQ link I gave you. How do I know? If you had looked at it you would NOT have written this:

imwrite(b,'C:\Users\Public\Videos\Sample Videos\pro\Newr\im%d.jpg',k);

imwrite() is not like sprintf() - it does not embed "k" into the filename string. You need to do it in two steps like the FAQ shows:

fullFileName = sprintf('C:/Users/Public/Videos/Sample Videos/pro/Newr/im%d.jpg',k);
imwrite(b,fullFileName);
