c#
//Get a picture as stream
FileStream imageStream = new FileStream(Path.GetFullPath(@"Data/Image.jpg"), FileMode.Open);
//Add picture to the shape collection
IPicture picture = slide.Shapes.AddPicture(imageStream, 373, 83, 526, 382);

c#
FileStream outputStream = new(Path.GetFullPath(@"Output/Result.pptx"), FileMode.Create, FileAccess.ReadWrite);
pptxDoc.Save(outputStream);
//Close streams and presentation
outputStream.Close();
imageStream.Close();
pptxDoc.Close();
