With json_decode every {} (object) will become an object(stdClass) and every [] (array) will become an array. So:

$data->data[0]->images[0]->source

is what you need, to reach the first image source.

Edit: since the second parameter of json_decode is true, it will become an associative array, and it will be like:

$data['data'][0]['images'][0]['source']

To get all the images:

$images = array();
foreach ($data['data'] as $d)
{
    foreach ($d['images'] as $i)
    {
        $images[] = $i['source'];
    }
}
