One of the easiest ways to create an attention-grabbing picture is with the use of props. Generally you don't have to worry too much about them being outlandish, even ridiculous items such as unicorn-floaties are sure to make a great impression and will get people talking. If you're less flashy, be sure to items with interesting patterns or colours that will make them stand out. Anything from an interesting pair of sunglasses, to an umbrella or even scuba gear can add a great deal to a picture.
