create the thumbnails of various images in vb.net

You don't say whether you want a VB.net solution or otherwise.

Programatically, you can iterate through each file in the directory and use the GetThumbNailImage() method to resize it.

It would look something like this...

Image.FromFile(ImageFilenameVar).GetThumbnailImage(newWidth, newHeight, ImageAbortCallbackProc, IntPtr.Zero).Save("ThumbnailSaveDir\" + ImageFilenameVar);

The above is C# but should easily translate to VB.NET

Anyway, GetThumbnailImage() is probably what you are interested in.
