To do this, you will have to use some LINQ to iterate through the document and get a reference to all the shapes in the document. The wps:spPr element you see in the above XML code is the xml element fo...

Now that you have a collection of all the shape references in the document. Loop through the collection with a foreach, and through each iteration create a Blip object. Set the Blip object embed value to the picture ID reference you captured earlier from the image part. Also create a Stretch object...
