Hi Rob,
Thanks for contacting us. Basically the url in the file parameter points to a temporary image download. It will only remain a valid url for a couple of days. The intention of the API is that you will save this file to your server if you need to hang onto it, or you can display it immediately (as it does in api-example.php that you've mentioned) using some simple PHP like:
<?php
echo '<img src="'.$_GET['file'].'" />';
?>
Alternatively the following Javascript can be placed directly into an HTML file in order to display the image:
<script>
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
document.write("<img src='"+getParameterByName("file")+"'>");
</script>
Please let us know if we can be of any further assistance!
