Google Map Makers Sprite in OSX not displaying - iphone

Question

I can't seem to get the my map markers to display when I use an image sprite on the iphone. They appear when I use the standard google map markers on iphone and when viewing the site in the desktop the sprite icons work fine.
Here is the code I use to create the markers, I am using Zepto but JQuery could as easily apply.
$.ajax({
dataType: 'jsonp',
url: myLocations.LocatorUrl,
timeout: 8000,
success: function(data) {
var infoWindow = new google.maps.InfoWindow();
var bounds = new google.maps.LatLngBounds();
$.each(data, function(index, item){
var data = item, pincolor,
latLng = new google.maps.LatLng(data.lat, data.lng);
var d = 'http://blah';
var pinImage = new google.maps.MarkerImage(d+"/assets/img/sprite.locator.png",
new google.maps.Size(24, 36),
new google.maps.Point(0,25),
new google.maps.Point(10, 34));
// Creating a marker and putting it on the map
var marker = new google.maps.Marker({
position: latLng,
map: map,
title: data.type,
icon: pinImage
});
bounds.extend(latLng); // Extend the Latlng bound method
var bubbleHtml = '<div class="bubble"><h2>'+item.type+'</h2><p>'+item.address+'</p></div>'; // Custom HTML for the bubble
(function(marker, data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker, "click", function(e) {
infoWindow.setContent(bubbleHtml);
infoWindow.open(map, marker);
});
markers.push(marker); // Push markers into an array so they can be removed
})(marker, data);
});
map.fitBounds(bounds); // Center based on values added to bounds
}, error: function(x, t, m) {
console.log('errors')
if(t==="timeout") {
alert("got timeout");
} else {
alert(t);
}
}
});

Got it. Turns out the images I was referencing were on localhost, when I swapped this to the actual IP address of my local machine it worked.
