Pardon my ignorance here but I cannot see any question in your post. However it would appear you might be asking how you did something to the photograph. To add an oval you could have done it by means of any graphics editor such as "the gimp" click here or even photoshop. Going to a further extreme it can even be done using MSpaint.
However there is no specific question in your post so I dont think anyone can really help any more than the above without some clarification.
