Powerpoint is a ppt file.
You can insert a powerpoint file into your web page but it is NOT compatible for everyone. Like Word and Excel, Powerpoint requires the proper software to view that file. If someone (like my Mom) does not OFFICE/Powerpoint or the free viewer installed on their machine the ppt file will not play.
Powerpoint does have the capability to convert to HTML or Flash. But Microsoft does a very poor job of both. Flash is HUGE and HTML is individual pages.
If you do want to use powerpoint, then DEFINITELY convert to HTML or Flash. And then use a container page for the HTML or let us know and we will help you insert the flash. (Flash can not be seen on apple products without using a different browser).
Ironically, our favorite CSB replacement web building software (Xara Web Designer Premium
) offers the ability to to everything that powerpoint does and produce very nice web presentations. You can even use that software to host a REMOTE PRESENTATION, a WEBINAR free of charge. h**p://presenter.xara.com/uk
