I am adding multiple images to a single paragraph as I need the pictures to be on the same line, but I couldn't find a way of adding margin/ space between each image.
IWParagraph firstParagraph = table[1, 0].AddParagraph();
foreach (var pic in item.Pictures)
IWPicture picture = firstParagraph.AppendPicture(pic);
picture.Width = 125;
picture.Height = 125;
