Setting up widget sharing is easy: you use our sharing tools just as you normally would, but you also to tell us the URL and preferred width and height of the SWF file. To do this, you just tag your page with Facebook-style meta tags. When AddThis shares your page to a supporting destination, that destination will read these tags and share your Flash object instead of just a link. If you don't control the page or can't add tags to it, you can also pass extra parameters to our APIs (though we recommend the tagging approach). For more information, please refer to Embedded Content Sharing.
