Upload & show ppt/pdf files. Directions..?

[eluser]Tilt[/eluser]
Hello people.

I am working in a project in wich a type of user can upload a ppt or pdf file. After that other users - same type or not - can view the file. I am thinking about doing this like the SlideShare kind of view, but people here doens't want the SlideShare API. Is it possible to do this? I 'm lost even about that. Didn't find nothing so especific in the user guide or even here.

I used the Upload Class and worked fine, but i still have no idea how to finish this. I suppose i have to use javascript, but if someone could point a direction of research or something i would appreciate.

Thanks Sorry i am not used to write in english.
