into a Frontpage website fairly easily. Just create a new folder in the web, and call it say, 'presentation'.
Then, in folder view, click on the folder and select 'Import' from the File menu. Import the presentation from the saved location on your hard drive. Now place a hyperlink on the page, selecting the file you placed in the web earlier. When a visitor clicks on the link his/her browser will download the file and display it in PowerPoint. They'll only be able to see the presentation if they have PowerPoint installed, or if they download the Microsoft Powerpoint viewer.
