Yes, you have to upload all the files to the web site where you will publish the presentation.
Point your link to the index.htm file.
I am not really that sure about preventing downloading of files. I unzip the files into a hidden folder without public access.
I have tried doing exactly what you said but it will not work.
Should I place the files in a specific place? Like at the root?
Thx Hollis for this answer! Works
