I have already posted articles on How to embed Powerpoint slideshows on your website. It required to go to their service each time you want to embed something and they used to give you Embed code. However Now , You can have Powerpoint shows, PDF and Word documents and it can be viewed on site itself as it opens layered translucent document viewer (Please note it’s different from Embedding)

SmartLook is an intelligent service which enables viewing of documents online without need to download it. This is different from embedding as it do not occupy your webpage space and opens another layered window on the page. It can open PDF, DOC and PPT extension files.

To install, it’s one time job. You need to install code they give for your doamin in the body tag of your website and rest all is monitored by smart look. To watch it in action visit : http://www.ismartlook.com/
