{
   // Opens the template Word document.
   using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Automatic))
   {
       // Variables to store the original width and height of each picture.
       float pictureWidth, pictureHeight = 0;
       // Find the picture with alternative text.
       WPicture picture = document.FindItemByProperty(EntityType.Picture, "AlternativeText", "Adventure") as WPicture;
       // Store the original width and height of the picture.
       pictureWidth = picture.Width;
       pictureHeight = picture.Height;
       // Open the new image file to replace the existing picture.
       FileStream imageStream = new FileStream(Path.GetFullPath(@"Data/Image.png"), FileMode.Open, FileAccess.ReadWrite);
       // Load the new image into the existing picture element.
       picture.LoadImage(imageStream);
       // Restore the original width and height to maintain the picture's dimensions.
       picture.Width = pictureWidth;
       picture.Height = pictureHeight;
       using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite))
       {
           // Saves the modified Word document.
           document.Save(outputFileStream, FormatType.Docx);
