HOW TO show just icons for Favorites in Bookmarks Bar

There is a question on the Super User forum from a guy who has a ton of bookmarks in his bookmark bar. Each one shows the full text which causes the bookmarks to run off the window in Google Chrome. He wants to know if he can have them show as icons only like in IE?

One possible way, according to a comment there, is to remove the bookmarks' names - by editing the names of existing Bookmarks in Bookmark Manager or removing the name while adding a bookmark.
