Thumbnail for Vimeo

Hi, i write a plugin to get Thumbnail images video title & description and its not really hard to get Vimeo big thumbnail without the API key.

the ID is in image url ex: http://i.vimeocdn.com/video/79702288_640.jpg

The ID is in the video url: https://vimeo.com/79702288

the video iframe src: //player.vimeo.com/video/79702288

the Vimeo regex from the video URL to get de ID is: /^.+vimeo.com\/(\d+)($|\/)/

regex for iframe src: /^.+vimeo.com\/video\/(\d+)($|\/)/;

And to be 100% sure to get the big image i use the api rest json
http://vimeo.com/api/v2/video/79702288.json
I a get the large thumbnail in the json : thumbnail_large
