ASP.Net page to display powerpoint thumbnails

Your best bet (if you want to embed the ipresentation in your web page is to convert it to Flash.  There are a number of free converters out there: AuthorPoint does a good job: http://www.authorgen.com/authorpoint-lite-free/powerpoint-to-flash-converter.aspx
ISpring does too: http://www.ispringsolutions.com/products/ispring_free.html
Just keep the presentation simple.
If you just want the presentation to open full screen when the thumbnail is clicked, simply save the file as a PPS and post that file and link the thumbnail to the file.

All I have to work with is office 2007 and VS 2008. Other tools, free or otherwise, would take months to acquire.

Thanks but that's not quite what Im looking for, and my requirements have changed some. On the ASP.Net page there is a file ipload control. Once the user finds and selects the powerpoint presentation they are looking for, the page will then display each slide form that presentation on lower 2/3 that asp.net page as thumbnails. Can this be done?

Or use VB:

This particular code was written to do something similar to what dodgerfan asked.

That is VB6 code which can not be used in ASP.NET.

Although same code could be written in VB.NET with Interop assemblies.
