$.getJSON(url, function(res) {
           var pages = res["query"]["pages"];
           $.each( pages, function( i, item ) {
               var info = item.imageinfo[0],
                   width = item.width;
           });
});

I want to receive image info via the API in json. The Sandbox looks fine: https://www.mediawiki.org/wiki/Special:ApiSandbox#action=query&format=json&prop=imageinfo&titles=File%3AExample.jpg&iiprop=timestamp%7Cuser%7Curl%7Csize

But running the query in real life, the imageinfo array is empty:

How would I properly iterate over the result objects?

I also note that the separator for iiprop is a pipe character not a comma and that this call does not require a POST.
