body: <p>I want to fetch images from other site and display on my site. I want to store that images in my side temporary only at time of showing on page , so that user think images are coming from my site.is it possible? How? Thanks in advance.</p>
  
  <p>ex:-
  imagine there are some graphs generated in a server (some network monitoring graphs like smokeping )and those graphs are stored in a folder as <code>.png</code> format.</p>
