Embeds media in Yahoo sports fantasy message boards. All you need to do is include a link to the media you want to display in your post/message and YES (Yahoo Enhancement Suite) will embed the content for you automatically. No more copying and pasting links!
Currently supports JPG/JPEG/PNG/GIF and YouTube videos.
YES simply embeds existing links to media on Yahoo's fantasy message boards and does not collect any user data.
