Figure and Floater can be used to put other objects into your FlowDocument. Figure is used for content that stands by itself. (I used a picture and Figure in the example below.) Floater will put content that is integrated into your text, but separate from it, such as a few words from a quote in the text that you want to stay with the entire quote. Putting images into WPF documents can be a lot of fun too, especially if you do it in VB.NET code rather than XAML, so I used an example that places a picture of Sirius the dog star into an anchored position with respect to the text.
Private Sub Window1_Loaded( _
ByVal sender As System.Object, _
ByVal e As System.Windows.RoutedEventArgs) _
Handles MyBase.Loaded
Dim aParagraph As Paragraph = New Paragraph
Dim aFigure As Figure = New Figure()
aFigure.Width = New FigureLength(200)
aFigure.Height = New FigureLength(200)
aFigure.Background = Brushes.DeepPink
aFigure.VerticalAnchor = FigureVerticalAnchor.ParagraphTop
Dim aImage As Image = New Image
Dim aBitmapImage As New BitmapImage
aBitmapImage.BeginInit()
aBitmapImage.UriSource = New Uri("C:\...\sirius.JPG")
aBitmapImage.DecodePixelWidth = 200
aBitmapImage.EndInit()
aImage.Source = aBitmapImage
aFigure.Blocks.Add(New BlockUIContainer(aImage))
Dim aSpan As Span = New Span
aSpan.Inlines.Add(aFigure)
aParagraph.Inlines.Add(aSpan)
aParagraph.Inlines.Add(New Run("Lorem ipsum ... etc.
Dim aFlowDocument As FlowDocument = New FlowDocument
aFlowDocument.Blocks.Add(aParagraph)
Dim aFlowDocumentReader As FlowDocumentReader _
= New FlowDocumentReader
aFlowDocumentReader.Document = aFlowDocument
Window1.Content = aFlowDocumentReader
End Sub

Like WPF itself, the possibilities here are endless. For example, not only do you have the Block types listed earlier available to you, but you can define your own Block type and put anything you can write code for into your FlowDocument. This article has just scratched the surface.
