Hi: I just download a free version of flash_page_flip from http://www.flashpageflip.com/ I set up a file structure like this, based on the package from the site: /book /book/index.php /book/js/ --> swfobject.js /book/swf/ --> Magazine.swf, Pages.swf /book/txt/Lang.txt /book/xml/Pages.xml How it works? I assume when it accesses from the this uri (http://www.finditreadit.com/afl/aflannualreport/aflannualreport2006/mode/book). It will loads Magazine.swf Magazine.swf then loads images as pages from the server to Pages.swf Why is it called dynamic uri? Because it is not based on file system in the server. It is a bit like model view controller used by rail. Access via dynamic uri http://www.finditreadit.com/afl/aflannualreport/aflannualreport2006/mode/book You will see a cycle there. That means the flash is still loading, but it never finish. Access via static uri (It is based on the paths of the server) http://www.finditreadit.com/test/all/aflannualreport/aflannualreport2006/book (I disable it, but it is tested.) It will work. My understanding: I assume when it access via static uri. The flash uses relative paths. That means I only need to specify parts of the file paths. While accessing dynamic uri, flash file must rely on full file path. So I assume Magazine.swf doesn't know where to find Pages.swf What about your thought?
