Hi,

       Image in xml in string format you can extract it by walk through the xml node.

Using XmlTextReader class you can read .i.e.

Lets take given sample

<Book>
    <BookName>C# Professional</BookName>
    <BookName>C# Cookbook</BookName>
    <ReleaseYear>2003</ReleaseYear>
    <ReleaseYear>2004</ReleaseYear>
    <Publication>Microsoft Press</Publication>
    <Publication>O 'Reilly</Publication>
</Book> 

Beow the code snippet

  XmlTextReader objXmlTextReader =
          new XmlTextReader(XMLFile1.xml");
    string sName="";
    while ( objXmlTextReader.Read() )
    {
      switch (objXmlTextReader.NodeType)
      {
        case XmlNodeType.Element:
        sName=objXmlTextReader.Name;
        break;
        case XmlNodeType.Text:
        switch(sName)
        {
          case "BookName":
          cboBookName.Items.Add(objXmlTextReader.Value);
          break;
          case "ReleaseYear":
          cboReleaseYear.Items.Add(objXmlTextReader.Value);
          break;
          case "Publication":
          cboPublication.Items.Add(objXmlTextReader.Value);
          break;
        }
        break;
      }
    }
