title: How to calculate the bounding box for a given lat/lng location?
body: <p>I have given a location defined by latitude and longitude.
  Now i want to calculate a bounding box within e.g. 10 kilometers of that point.</p>
  
  <p>The bounding box should be defined as latmin, lngmin and latmax, lngmax.</p>
  
  <p>I need this stuff in order to use the <a href="http://www.panoramio.com/api/" rel="noreferrer">panoramio API</a>.</p>
  
  <p>Does someone know the formula of how to get thos points?</p>
  
  <p><strong>Edit:</strong> Guys i am looking for a formula/function which takes lat &amp; lng as input and returns a bounding box as latmin &amp; lngmin and latmax &amp; latmin.
  Mysql, php, c#, javascript is fine but also pseudocode should be okay.</p>
  
  <p><strong>Edit:</strong> I am not looking for a solution which shows me the distance of 2 points</p>
