You see I have seen lots of blog when they reblog the image becomes click-through with their link on it, so doesn't matter whose link was on the image but once they reblog it, their link is on it. I wanna know how they manage to do it, because Tumblr doesn't give the option when you reblog, it's got something to do with the coding. If someone can please help me with this, all the help is appreciated. Thanks!!!
