Plug-ins are platform-specific components for pages. Originally designed for Netscape Navigator 2.0, they are supported in Microsoft Internet Explorer 3.0 and higher as well. If you have a plug-in that you want to insert on the page, in the FrontPage Editor, on the Insert menu, point to Advanced and then click Plug-In. Enter a reference to the plug-in data file you want to use, and set the optional size and alignment parameters. When you press OK, a placeholder graphic will be inserted for the plug-in. You preview a plug-in in the FrontPage Editor’s Preview tab (if you have Microsoft Internet Explorer, version 3.0 or higher, installed) or by choosing Preview in Browser on the FrontPage Editor’s File menu.
