How to link all images to posts

By default, when you add an image to a post the image is hyperlinked to its url e.g. /wp-content/uploads/blablabla….

How do we change this hyperlink to the posts url instead ?

I know I can do it one by one but thats a long process because I’ve got loads of posts which is going take a hell of a lot time.

Any hack or plugin for this ?
