I did this via C#;

    // BMP, GIF, JPEG, PNG, TIFF
using (System.Drawing.Image img = System.Drawing.Image.FromFile(imgPath))
{
    using (MemoryStream ms = new MemoryStream())
    {
        img.Save(ms, img.RawFormat);
        imgNode.Attributes["src"].Value = "data:image/" + imgName.Substring(imgName.LastIndexOf('.') + 1) + @";base64," + Convert.ToBase64String(ms.ToArray());
    }
}
