Upload image to parse using Titanium

Hi, What is the parse class url that I should set to upload image from Titanium to parse? Currently my url is https://api.parse.com/1/classes/UserInfo. But I know I shouldn't be using this and must be using something like https://api.parse.com/1/files/photo.jpg. The issue is that I don't understand how the second url works. Can anyone please explain to me that?
