Trying to adapt the $.getJSON Flickr example:
$.getJSON(\"http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jso
This could be simplified by choosing the 'url_m' extras parameter and per_page parameter...
extras=url_m&per_page=4
Then all you need is this within the loop...
$("").attr("src", item.url_m).appendTo("#images");
