Google Maps Static API is asking for API Key
<p>When using the google maps static API service, all my requests are showing up as a 403 Forbidden. When taking a look at my request, I notice this error message: "The Google Maps API server rejected your request. This service requires an API key."</p>

<p>The code that is calling the service is below:</p>

<pre><code>&lt;img src="http://maps.googleapis.com/maps/api/staticmap?center=Albany,+NY&amp;zoom=13&amp;scale=false&amp;size=600x300&amp;maptype=roadmap&amp;format=png&amp;visual_refresh=true" alt="Google Map of Albany, NY"&gt;
</code></pre>

<p>I've used the static map service before and it worked fine and easily. But for some reason, all my requests show up as a 403 now? I've never had to use an API key in the past. If I do use an API key with this call, it works.</p>

<p>What is going on here?</p>
