GetThumbNailImage()

Upon using this method, I have run across something I did not know.  All of my thumbnails were turning out really bad with some horrible looking compression.  As it turns out some digital cams imbed a thumbnail inside the image, and the GetThumbNailImage() method returns a thumbnail from the imbedded thumbnail as pointed out in this article. 

So a workaround for me has been to load the images in PS and do a Save For Web, this shrinks the original Image and nukes the imbedded thumbnail.  Now if I could only figure out how to pull the imbedded thumbnail instead of calling GetThumbNailImage().
