Vista - In Visual Basic 2008 create aspx web pages programmatically

I am working with Visual Studio or alternately with Expression Web. I need
to create about 50 aspx pages with about 1200 thumbnali images, typically
arranged in three to four groups per page, having hyperlinks to the
corrtesponding full size images.

Can anybody point me to locations in MSDN or elsewhere giving the references
to attach, the commands & objects for creating or opening the pages and
possibly available classes?

I have done equivalent things with Excel where the corresponding references
workboook & worksheet commands, etc, are widely available.

Any direction would be appreciated.
