content fetcher plugin for yourls, source is available

I need a yourls plugin, which enhances the core function to get a text abstract and images from the destination page and save both as file. it should be possible to select the image file if more then one image on the destination url is available what is yourls: YOURLS is a small set of PHP scripts that will allow you to run your own URL shortening service (a la TinyURL). You can make it private or public, you can pick custom keyword URLs, it comes with its own API. You will love it. since yourls is opensource, you may check the wiki for existing plugin and extension examples.
