Hi,

You can use the following code to insert the slide element to add extra images to the album;

Private Sub InsertImage(ByVal jpegURL As String, _
                            ByVal dURL As String, _
                            ByVal title As String, _
                            ByVal width As Integer, _
                            ByVal height As Integer)

    Dim doc As New XmlDocument
    Dim filePath As String
    filePath = "xml file path"

    doc.Load(filePath)

    Dim root As XmlNode = doc.DocumentElement

    Dim nav As Xml.XPath.XPathNavigator = doc.CreateNavigator

    nav = nav.SelectSingleNode("/flash_parameters/album")  ' Select the album element

    nav.AppendChildElement("", "slide", "", "")  ' add the slide element into album

    nav = nav.SelectSingleNode("/flash_parameters/album/slide[last()]")   ' select the last inserted slide element

    ' add attributes to the selected/last inserted slide element
    nav.CreateAttribute("", "jpegURL", "", jpegURL)
    nav.CreateAttribute("", "d_URL", "", dURL)
    nav.CreateAttribute("", "transition", "", "0")
    nav.CreateAttribute("", "panzoom", "", "1")
    nav.CreateAttribute("", "URLTarget", "", "0")
    nav.CreateAttribute("", "phototime", "", "2")
    nav.CreateAttribute("", "url", "", "")
    nav.CreateAttribute("", "title", "", title)
    nav.CreateAttribute("", "width", "", width)
    nav.CreateAttribute("", "height", "", height)

    doc.Save(filePath)   ' save the xml file
End Sub

Hope this helps... :)

Apart from Jasmin's answer, here is another way using Linq to XML. Advantage is shorter code as you will see.

C#

XDocument xDoc = XDocument.Load(filePath);
            XElement albumElem = xDoc.XPathSelectElement("//slide[position()=last()]");

            albumElem.AddAfterSelf(new XElement("slide",
                new XAttribute("jpegURL", "some value"),
                new XAttribute("d_URL", "some value"),
                new XAttribute("transition", 0),
                new XAttribute("panzoom", 2)));  //Add more attributes as per your need.

            xDoc.Save(filePath);

As you can see the code is concise and readable. Hope it helped.
