Download image in text document

Question

Im developing a wpf application that simply inserts an image into a word document. Every time a word document is opened, I want the image to call the image from the server, for example (server.com/Images/image_to_be_insert.png) My code looks like this:

 Application application = new Application();
 Document doc = application.Documents.Open(file);

 var img = doc.Application.Selection.InlineShapes.AddPicture("server.com/Images/img.png");
 img.Height = 20;
 img.Width = 20;

 document.Save();
 document.Close();

Basically, what my code does is upload the image and then add it to the document. What I want to do is that I want the image to be downloaded from the server whenever a text document is opened.

Instead of using Office Interop libraries, you can achieve this using the new OpenXML SDK, which does not require MS Office to work.

Requirements

OpenGML NuGet Visual Studio: DocumentFormat.OpenXml

:

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Vml;
using DocumentFormat.OpenXml.Wordprocessing;

using (WordprocessingDocument package = WordprocessingDocument.Create(@"c:/temp/img.docx", WordprocessingDocumentType.Document))
{
    package.AddMainDocumentPart();

    var picture = new Picture();
    var shape = new Shape() { Style="width: 272px; height: 92px" };
    var imageData = new ImageData() { RelationshipId = "rId1" };
    shape.Append(imageData);
    picture.Append(shape);

    package.MainDocumentPart.Document = new Document(
        new Body(
            new Paragraph(
                new Run(picture))));

            package.MainDocumentPart.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/image",
   new System.Uri("https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png", System.UriKind.Absolute), "rId1");

    package.MainDocumentPart.Document.Save();
}
