If you want it available to people who do not have Powerpoint installed, opening the file in Open Office and using the Save-As-HTML function there will produce relatively decent files. (Never, ever go near that option in any Microsoft product)
Microsoft applications tend to generate heaps of unnecessary formatting in the HTML pages, but Power Point does a pretty good job. I have used Power Point to create a slide show on the net, and it does work.
There are several things you need to watch out for. First, it targets Internet Explorer and may not work properly in other browsers. The front page, generated from Power Point, is just a little Javascript that senses the browser. If it sees IE, then it just continues on, but if it's anything else, it shows a warning.
Power Point documents, in HTML, are frames based. This isn't a problem unless you have a free site. Some web hosts allow a special tag to suppress banners in frames pages, but Bravenet is not one of them.
Finally, for uploading purposes, saving your Power Point file with the "Save As Web Page" will create a single HTML file, for the entry. Plus, it will create a folder with a mess of support files. The number of files depends on how big the document is. You will need to upload the entry page and the entire support folder.
I have a very simple two frame example on my site at "http://www.k7mem.com/Party_Time.htm". It's not much, but it does illustrate that it can be done. It's a lot of work and requires a lot of overhead if you need to make changes. Generally, it isn't worth the bother.
Setting up a JavaScript slide show is generally not a task for a novice. If you do a Google search, you may find other scripts that are easier to use.
A major drawback of using JavaScript, of course, is that visitors who have disabled scripting will not be able to see the slide show. You could also code a slide show using meta refresh tags; fewer people are likely to turn off those redirects, although they do have that option.
If you have the Premium Hosting Package, you might be able to find a PHP script that will do the job. This would have the major advantage that because it's server-side rather than client-side, it should work for everyone who visits your site.
There is a powerpoint file at
http://www.icann.org/tlds/org/presentations/isoc-presentation.pps
(I just searched for "download ppt")
At
http://whomever.bravehost.com/presentation.html
is a Open Office HTML version of this file. (I haven't got PowerPoint installed on this computer, so there may be deficiencies I'm not aware of)
