ShellBrowserGetThumbnailBitmap(Size, GetThumbnailCallback, Object, Int32) Method

Asynchronously extracts the thumbnail image of the currently active shell object in the requested size. Only for folders on Vista or later the size will always be quadratic with side length being the smallest of either p_Size.Width or p_Size.Height, to avoid a stretching - use the synchronous call GetThumbnailBitmap(Size) if you'd like to explicitly specify the dimensions
