I have a code here.

```
start_path = fullfile(matlabroot, '\toolbox\images\imdemos');
% Ask user to confirm or change.
topLevelFolder = uigetdir(start_path);
if topLevelFolder == 0
    return;
end
% Get list of all subfolders.
allSubFolders = genpath(topLevelFolder);
% Parse into a cell array.
remain = allSubFolders;
listOfFolderNames = {};
while true
    [singleSubFolder, remain] = strtok(remain, ';');
    if isempty(singleSubFolder)
        break;
    end
    listOfFolderNames = [listOfFolderNames singleSubFolder];
end
numberOfFolders = length(listOfFolderNames)

% Process all image files in those folders.
for k = 1 : numberOfFolders
    % Get this folder and print it out.
    thisFolder = listOfFolderNames{k};
    fprintf('Processing folder %s\n', thisFolder);

    % Get PNG files.
    filePattern = sprintf('%s/*.png', thisFolder);
    baseFileNames = dir(filePattern);
    % Add on TIF files.
    filePattern = sprintf('%s/*.tif', thisFolder);
    baseFileNames = [baseFileNames; dir(filePattern)];
    % Add on JPG files.
    filePattern = sprintf('%s/*.jpg', thisFolder);
    baseFileNames = [baseFileNames; dir(filePattern)];
    numberOfImageFiles = length(baseFileNames);
    % Now we have a list of all files in this folder.

    if numberOfImageFiles >= 1
        % Go through all those image files.
        for f = 1 : numberOfImageFiles
            fullFileName = fullfile(thisFolder, baseFileNames(f).name);
  pathname = strcat('C:\\xampp\\htdocs\\PACS_Client\\cbir_matlab\\ano\\');
  outputBaseFileName = sprintf('%3.3d.jpg',f);
  outputFullFileName = fullfile(pathname, outputBaseFileName); 

  fprintf('Processing image file %s\n', fullFileName);
  im=imread(fullFileName);
  imshow(im);
  data = im;
  imwrite(data,[pathname,outputBaseFileName]);
        end
    else
        fprintf('     Folder %s has no image files in it.\n', thisFolder);
    end
end

```
