Looking for an Image Gallery Plugin that converts a list of URL's into a Gallery

Hi. I’m looking for a plugin that turns a list of images inside a post, (their URL’s), into a gallery. Ideally, it would be a shortcode that just does [plugin]http://image.jpg http://image2.jpg etc.[/plugin] and turns that into a gallery with features like lightbox or whatever. If it doesn’t need the shorcode, and just scans the posts, even better! Any suggestions??

P.d.. It also can be a plugin where you set up different galleries from a image list. All I have is a big pile of posts, with a big pile of image urls each! Thanks
