try to save the powerpoint as a website? I think there should be such option in the File menu ("Save as Web Page"). Once you have the pages, simply upload them to a website... and you have an online presentation.

It's a pretty big slide show in terms of file size, it's full of pictures and has background music playing throughout. I tried converting it to MPG so that I could upload it to YouTube, but the MPG ended up about 300 megabytes and YouTube's limit is 100. Is there any other way to do this?
