Where do I start if I want to create Facebook app to customize profile picture? I could not find documentation for that.
I see someone made an app to set #starwars themed profile picture. And below, there's a suggestion to customize my own profile photo:
Clicking Try it
button, I get such dialog:
Anyone knows where it's documented or how to create similar app? Thanks.
Update: Yes I know about Facebook API to get and set profile picture, but I'm interested if there's a way to create these new style apps which opens on top of feed as a dialog? And also how to add these "Try it" buttons in news feed?
That´s an official App from Facebook, you can´t create something like that on your own. Of course you can create an App to authorize the User, load his profile picture and change it, but you can´t directly set a new one like in that official App.
There´s probably hundreds of threads about this already, for example:

About that "try now" button, you could try the suggestions i made in another thread: Facebook Post Call to Action button using Graph API
