This WYSIWYG (What You See Is What You Get) program generates HTML and JavaScript code to open an URL in a new (PopUp) window. You can specify the properties of the new window, including its size, attributes (whether it is resizable, has a menu bar, and so on), and name. For example, you can use it to open a larger image in a separate window when the visitor clicks a thumbnail image. You can make the new window with exact size?of the image.
