When I visit any page containing some animated `gif`s (Google+, 9gag etc), all those seem to start loading. My bandwidth is limited and I don't want those to be downloaded unless I really want to view. I have seen some plugins which just stop *animation* but the image itself is *downloaded* anyway. 9gag.com had initially this feature which just showed a static image (if it is an animated gif) and started downloading only after I clicked on it (they have removed it now). 

So, is there any plugin which can stop *downloading* gif? Or, do I need to write an extension? Any suggestion?
