this is what i have tried to use so far to save captured image but it hasnt worked...
counter = 1;
baseDir = 'C:\Users\Nakk\Documents\MATLAB';
baseName = 'Nakk_'; %Nakk is the name i have chosen for the image files
newName = [baseDir baseName num2str(counter) '.jpg'];
while exist(newName,'file')
counter = counter + 1;
newName = [baseDir baseName num2str(counter) '.jpg'];
end
imwrite(img, newName);

counter= 1;
for i=1:N
Face=imcrop(img,bbox(i,:));
axes(handles.axes2);
imshow(Face);
savenam= strcat('E:\matlab\Face Recognition & Image Processing System\R_TrainDatabase', num2str(counter));
baseDir = 'E:\matlab\Face Recognition & Image Processing System\R_TrainDatabase';
newName = [ baseDir savenam num2str(counter) ' .jpg'];
handles. face= face;
while exits(newName, 'file')

savenam= strcat('E:\matlab\Face Recognition & Image Processing System\R_TrainDatabase', num2str(counter));
That already has counter as part of it, and then you put the counter in again
newName = [ baseDir savenam num2str(counter) ' .jpg'];

Notice that your baseDir does not end with a file separator, such that Matlab checks for the files "C:\Users\Nakk\Documents\MATLABNakk_1.jpg" etc.
Better use fullfile instead of the concatenation of the path with [ and ]:
newName = fullfile(baseDir, sprintf('%s%d.jpg', baseName, counter));
I prefer sprintf instead of num2str for such cases.

Please show your code -- all the parts of how the image is captured and saved.
