PdfDocument document = PdfReader.Open(sourcePdfPath, PdfDocumentOpenMode.Modify);
PdfPage newPage = document.AddPage();
XImage image = XImage.FromFile(imagePath);
XGraphics gfx = XGraphics.FromPdfPage(newPage);
gfx.DrawImage(image, 0, 0, newPage.Width, newPage.Height);
if (pageIndex < document.PageCount - 1)
{
    document.InsertPage(pageIndex + 1, newPage);
}
else
{
    document.AddPage(newPage);
}
