Problem is, when I apply Gabor on a single image, I get perfect results, but when I access the entire images , it only operates on the last image in the folder, most probably others are over written, how can I access each individual image in a folder??

See the FAQ for code examples: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F like this:

myFolder = 'C:\Documents and Settings\yourUserName\My Documents\My Pictures';
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.jpg');
jpegFiles = dir(filePattern);
for k = 1:length(jpegFiles)
  baseFileName = jpegFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  imageArray = imread(fullFileName);
  imshow(imageArray);  % Display image.
  drawnow; % Force display to update immediately.
end

in imageArray I got my images , now if I want to apply something on the ist image then on the second image and so on, shall I proceed with this : imageArray(1) imageArray(2) this gives me the numeric value in the matrix, but I want the particular image at location 1, and then perform some task , then on 2,, and so on How can I do this?

Not exactly sure what you're describing, but yeah, that's all possible (whatever it is). Just do normal MATLAB programming commands. http://www.mathworks.com/matlabcentral/answers/8026-best-way-s-to-master-matlab
