Insert Image to Word

I'm not sure how you can do that with the mentioned control, however here is how you can do this with VB.NET component for word documents:

DocumentModel doc = DocumentModel.Load("Sample.docx");

foreach (Picture pic in doc.GetChildElements(true, ElementType.Picture).Cast<Picture>().ToArray())
{
Layout picLayout = pic.Layout;
int width = (int)LengthUnitConverter.Convert(picLayout.Size.Width, LengthUnit.Point, LengthUnit.Pixel);
int height = (int)LengthUnitConverter.Convert(picLayout.Size.Height, LengthUnit.Point, LengthUnit.Pixel);

using (Image image = Image.FromStream(pic.PictureStream))
using (Bitmap bitmap = new Bitmap(image, width, height))
{
MemoryStream newPicStream = new MemoryStream();
bitmap.Save(newPicStream, image.RawFormat);
Picture newPic = new Picture(doc, newPicStream);
newPic.Layout = pic.Layout;
pic.Content.Start.InsertRange(newPic.Content);
pic.Content.Delete();
}
}

doc.Save("Sample.docx");
