Cor

Thanks, i can see this working, however in my application i want to
store the image as an XmlNode, the complete xml file looks like the
following:

- <Tags>
- <Tag id="e2c0fde4-f540-43e9-b0ac-0d7c94f2196f">
  <Checked>Unchecked</Checked>
  <Text>Test Tag</Text>
  <Expanded>True</Expanded>
  <Image type="base64Binary">JFIF

HHC    $.' ",#(7),01444'9=82<.342C
  2!!22222222222222222222222222222222222222222222222222

  </Tag>
  </Tags>

The example you have given illustratess how to store the image as a
file in it's own right and as in xml format through a dataset, my
problem is that i want it to be a tag within an existing xml document.

The problem is that somewhere and i am not sure where there is data
being lost i believe when turning the image into a string:

            Dim ms As New IO.MemoryStream
            Me.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
            Dim imageBytes() As Byte = ms.GetBuffer
            Dim imageString As String =
System.Text.Encoding.UTF8.GetString(imageBytes)
            Dim imageNode As XmlElement = CreateAppendElement(tagNode,
"Image")
            imageNode.SetAttribute("type", "base64Binary")
            imageNode.InnerText = imageString

I cannot find any references that create an xml representation of an
image as a part of a larger xml file.

Thanks

Blu.
