Directory of links (like categories), easily chosen in post ?

Is there a free plugin or any way of doing this easily?

I now add link, name for the link and a thumbnail-image to each post. I would like for it to be set easier, to like have a directory of all of these so I only have to manage all of that once per destination.

And then for each post only have to click the name of the destination and the link, name and thumbnail will be on auto since it’s already put into a directory.

I have seen this be done in a coupon-website, but I’m not sure how to do it.
