Eric, you're absolutely right :) I've just published a lighter version of the original code (it doesn't work anyway, now even if I make the same ajax call it doesn't work): http://jsbin.com/vexeq/7/edit?html,output
After execution, you'll find this in console.log: Uncaught TypeError: Cannot read property 'photos' of null I don't think it is a parseJSON error, because in the original implementation I use the same method to parse other json string and it works.
