        break;
    }
    
    //Read image data into a memory stream
    using (MemoryStream ms = new MemoryStream(imageData, 0, imageData.Length))
    {
        ms.Write(imageData, 0, imageData.Length);

        //Set image variable value using memory stream.
        newImage = Image.FromStream(ms, true);

Try to Deserialize the XML document and convert the byte[] to image.

Hi,
this worked for me:

C#

private void Form1_Load(object sender, EventArgs e)
{
    string s = "/9j/4AAQSkZJRgABAgEBLAEsAAD ..."; // XML photo as string
  pictureBox1.Image = Base64ToImage(s);

}
static Image Base64ToImage(string base64String)
{
    byte[] imageBytes = Convert.FromBase64String(base64String);
    MemoryStream ms = new MemoryStream(imageBytes);
    return Image.FromStream(ms, true);
}
