listview remote images

I've got the below bit of code which pull back a list of the users facebook contacts along with their profile picture, however the images are not loading for each user, it is only showing the images for a few users.

fb.requestWithGraphPath('me/friends', {
        fields : 'first_name,last_name,id,installed,picture.width(120).height(120),gender'
    }, 'GET', function(e) {
        if (e.success) {
            var d = JSON.parse(e.result);
            var pData = [];
            var iData = [];
            var row = d.data;
            row = row.sort(sortByName)
            for (var i = 0; i < d.data.length; i++) {
                var img = row[i].picture.data.url
                if (row[i].installed) {
                    pData.push({
                        properties : {
                            title : row[i].first_name + " " + row[i].last_name,
                            id : row[i].id,
                            image : img,
                            gender : row[i].gender,
                            accessoryType : Ti.UI.LIST_ACCESSORY_TYPE_DISCLOSURE
                        },
                        template : Ti.UI.LIST_ITEM_TEMPLATE_DEFAULT
                    });
                } else {
                    iData.push({
                        properties : {
                            title : row[i].first_name + " " + row[i].last_name,
                            id : row[i].id,
                            image : img,
                            accessoryType : Ti.UI.LIST_ACCESSORY_TYPE_DISCLOSURE
                        },
                        template : Ti.UI.LIST_ITEM_TEMPLATE_DEFAULT
                    });
 
                }
            }
            var play = Ti.UI.createListSection({
                headerTitle : 'Play with Facebook Friends',
                items : pData
            });
 
            var invite = Ti.UI.createListSection({
                headerTitle : 'Invite Facebook Friends',
                items : iData
            });
            var listView = Ti.UI.createListView({
                sections : [play, invite],
            });
            self.add(listView)
        } else {
            alert("Facebook Error");
        }
    })

The images are stored in var img = row[i].picture.data.url and pushed into the data array but not all images are loading
