Obtaining Image from ms-word gave me headache for a week. MS-Word contains two type of shapes: Shape and InlineShapes.
Shape refers to the objects inserted as object like Chemical Equations, Microsoft Equations, while inline shapes refer to images inserted, drawings etc. Following code provides an way to save both such files.
An updated version of the code will be republished later.
