 Languages can have multiple dictionaries, configured in the "Languages" link on the homepage.  Each dictionary is shown as a small tab.  For this demo, English has been configured with two dictionaries.  The second dictionary will open a popup window.  If you have many dictionaries, the extra ones will be shown in a small list box next to the tabs.
 
 1.2 Images
-Lute can do a simple image search for terms.  Next to the Sentences tab is a small image button.  If you click on it, you'll see some happy elephants (if you clicked on elephant!).  If you click on one of the images shown in the list, that image is saved in your data/userimages folder.  When you hover over the word in the reading pane, that picture is included in the word hover.  Try adding an image for your elephant by clicking on the term, clicking the eye icon, and clicking a picture you like.  Then hover over your elephant.
