SlideShare is a website where you can host and share presentations. You can upload all your slide shows , and find / download interesting presentations.
I increasingly use it on this website to make my slide presentations more easily and readily accessible on-line.
My slideshows can be accessed on the SlideShow website itself or I can embed them in my own site as below:
A Slidecasting feature is also available that is a multimedia format for viewing slide decks synchronized with an audio file. It is for conference talks, musical slideshows, audio picture books or whatever else you can imagine.
