How to apply this effect on a picture?

I've been wondering for a long time, how do you add these like shapes on pictures with a white exterior… Http://kevvn.tumblr.com/post/47303787974
Is there a free website that lets you do it? Is there an iphone app?

Nice effect! Picmonkey.com is your savior. I'm telling you, it has like the coolest effects some even better than that one. No you don't have to download or sign up for an account to use it. I don't have one but I use it all the time. Just upload whatever image and on the side click on effects and just play around to get the look you want. The effects on Picmonkey that that looks similar to are "frost", "radiance", and "bokeh".
