JavaScript

var data = [];

for (var i = 0; i < 10000; ++i) {
    data.push({
        image_src: 'http://lorempixel.com/40/40/business/?' + Math.round(Math.random()*100)
    });
}

document.querySelector('#list').data = data;

// the only way it works for me is the following:
var mainPanel = document.querySelector('#hPanel');
var toolbar = document.querySelector('#toolbar');
var list = document.querySelector('#list');

var contentHeight = mainPanel.clientHeight - toolbar.clientHeight;
//list.style.height = contentHeight + 'px';
