title: Different Markers in Google Maps with gmaps4rails
body: <p>With <a href="https://github.com/apneadiving/Google-Maps-for-Rails" rel="nofollow">gmaps4rails</a> there is a way to <a href="https://github.com/apneadiving/Google-Maps-for-Rails/wiki/Control-what-I-display" rel="nofollow">define a custom marker</a>. But the same one is then shown for each database entry.</p>
  
  <p>How would I show a different marker for each database entry, like in Google Latitude? Preferably through their own database column or through a sprite, if there are only pictures for categories/groups and not individual users.</p>
