There is such a plugin:
Gallery Magic. It's very easy in use and works with all TGP-style (e.g.
adultsiteskins) and Pinterest-style WordPress themes (e.g.
pinboard) because it allows to automatically generate the featured images (post thumbnails) too.
How does it work.
Add a new post or open the existing one and click the "Gallery Magic Shortcode" button (marked with a red square on the picture below).
The Gallery Magic popup box will appear. Enter the URL of the HTML page which does contain a gallery you want to copy, then click the "Insert Gallery Magic Shortcode" button.
The gallery shortcode will be inserted into your post.
Now simple save or update the post and Vualá, your gallery is here!
Get it for only $29.95 
The plugin license is unlimited and the code is non-encrypted.
