== Image == 

 The image at the top of the article contains internal links as dotted lines.  But those links aren't part of the suffix tree, they are part of the method of constructing the tree (and they are used in Ukkonen's linear time construction method while Weiner's method of linear time construction uses a different data structure.)  When I first started on the article I couldn't make sense of them even though I spent some time on it (I had to get a book listed in the references to find out what they were for.)  Since they aren't part of the tree (once it is constructed they can be discarded even if you are using Ukkonen's algorithm) I think we should get a diagram that doesn't contain the internal links and we can save the current image for discussing Ukkonen's algorithm.
