I don't know very much about this kind of software so I am hoping you guys and help. I need a script or program to put on my website so I can put one pdf and make it viewable where the pages digitally turn. I think you see it a lot in online magazines and catalogs. I was able to find many examples of payed programs like http://www.3dissue.com/ but they seemed to be $500 or more. I only need to have one pdf file so I am looking for a free version. Any ideas?
