store loaded image in a variable and Use setappdata and getappdata .
axes(handles.axes2);
image(a);
setappdata(0,'image',a);
%%%
now get this image and load it in anyother axes or whatever u want.
im=getappdata(0,'image');
axes(handles.axes3);
image(im);

This is fine but the problem I'm facing is to get the image after zooming i.e. I firstly loaded the image on axes and then performed the zoom operation. Now I only want the zoomed portion of the image. How can I do that.

Try using getframe(). Or get(hAxes, 'CData');

Naman, just like I told you. Look at this code:
close all;
im=imread('cameraman.tif');
subplot(1,2,1);
imshow(im);
subplot(1,2,2);
imshow(im);
size(im)
zoom(8);
zoomedImage = getframe(); % Get zoomed portion that is visible.
size(zoomedImage.cdata)
figure; % Bring up separate figure.
imshow(zoomedImage.cdata);
Do you see how in the second figure it is only the zoomed, visible portion of the image from figure 1 that was captured and is being displayed? From your post it sounds like you tried getframe() and it did not work for you for some reason. To fix it I'd have to see your code.
