I need to place a powerpoint presentation inside a web page for the user to use (interactively, check the slides without downloading) what is the best option to do this, do i have to convert it to any format?
Well, to view the PowerPoint file they’ll have to download it in essence to actually view it…
I assume you mean you’d like to embed the Slideshow within a page obviously that can cause issues if the user doesn’t have the correct ‘helper applications /plugins’ and isn’t guaranteed to work. There is another possibility you could convert it to another format like Flash.
Albeit to embed theoretically you would use OBJECT though I am not sure it would work without the correct browser/viewer combo.
