Anyone know if it's possible to create a preview of a PDF file using PHP? With GD perhaps?

With Adobe Acrobat Reader being a free plug-in for popular web browsers, is there really a need to use php to build an image preview when you can easily open the pdf document on the web page itself?

Well, it will be sized down to "thumb nail" size, too act and act more like an icon for the pdf. So yeah, there is a need..
