            using (WordprocessingDocument document = WordprocessingDocument.Open(fileName, false))
            {                    
                var run = document.MainDocumentPart.Document.Descendants<Run>().ToList();
                foreach (var eachrun in run)
                {              
                        var pic = eachrun.Descendants<Picture>().ToList();
                        foreach (var eachshape in pic)
                        {
                           --your code---
                        }                       
                }
