If you are wanting a self-running slideshow presentation, then you will need to use a 3rd party application such as slideshare, ispring, or avs4you to convert the slideshow to flash or video file. If you have Powerpoint 2010 then you can save it as a .wmv file and either use the Spruz video hosting option (requires upgrade) or upload it to YouTube and embed the YouTube video on your website. Hope this helps.
