You've decided you only want to get photos of london. Use the data option of the $.ajax function to pass a location option. Get the location from the data-location on the #tour element using the data method.
DOM :
<div id="tour" data-location="london">
<button>Get Photos</button>
<ul class="photos">
</ul>
</div>
JS:
$(document).ready(function() {
var el = $("#tour")
