2) Navigating the site is very simple

To view paintings, click on the left panel and choose a theme (e.g. Harvard Square, Casablanca)
like in our example below, "Winthrop Park- Harvard Square".
You then view a page with thumbnail pictures of all the ones included that theme (here only four are shown)
By clicking on the one of your choice, you get a full picture rendition.
At this point you can see at the bottom right and left of the picture two small green arrows which, when
passed over with your mouse turn red to allow you to view all the large pictures of that theme going forward or backward!
