The short answer is that no, you can't do that, but yes, you can as well.
If that sounds odd, let me explain.
PowerPoint animations will normally be rendered as static images when published for the web and text fades, slide ins and other animations will usually be lost.
A simple silde to slide view is easy to obtain, but you will lose your animations and effects when publishing to a web page.
What you can do is upload the file as a PowerPoint presentation and provide a download link to it, so that your visitors can download it and view it on their own PC. If you do that, make sure you provide a link to the PowerPoint viewer for those who do not have the program installed. Check out the Microsoft.com site and look in the Office >> downloads section to find the PowerPoint viewer.
