Hello Dear respected Walter

thank you for your tips. i tried this code according to your tips as given below.

   function D3_D_Callback(hObject, eventdata, handles)
myFolder = 'C:\Users\khanm\Desktop\image files';
if ~isdir (myFolder)
   errorMessage = sprintf ('Error: The following folder does not exist:\n%s',myFolder);
   uiwait (warndlg (errorMessage));
   return;
end
filePattern = fullfile (myFolder, '*text');
textFiles = dir (filePattern);
for k= 1:6
    baseFileName = textFiles(k) .name;
    fullFileName = fullFile (myFolder, baseFileName);
    fprintf (1, 'Now reading %s\n', fullFileName);
    imageArray = imread(fullFileName);
    imshow(imageArray); %display image.
    drawnow;
end
when i run the GUI the i found error on command window given below
**Index exceeds matrix dimensions.
Error in Text>D3_D_Callback (line 87)
    baseFileName = textFiles(k) .name;

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in Text (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)Text('D3_D_Callback',hObject,eventdata,guidata(hObject))

i wanna show all the images one by one using slider or push button but i am still unable to found the image.
