ITextSharp - Calling AddImageToPage() With The The Optional Pages Parameter Will Add The Image To All Pages Though?

I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF

Dim Pages() As Integer
Pages = New Integer() {1, 3}
PdfManipulation2.AddImageToPage(..., Pages)

Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.
