title: image manipulation in php or jquery?
body: <p>For a learn-as-I-code game that I'm designing, I have a pretty rudimentary map:</p>
  
  <p><a href="http://www.dixieandtheninjas.net/dynasties/images/dynasties_map_2.jpg" rel="nofollow">http://www.dixieandtheninjas.net/dynasties/images/dynasties_map_2.jpg</a></p>
  
  <p>I want to allow manipulation of the map in some of the following ways:</p>
  
  <ul>
  <li>Have the code place a dot on the map where the player is located (sql
  query to determine region number) </li>
  <li>Have the code recolor regions which
  are hostile to the player (sql query)</li>
  </ul>
  
  <p>While I think that this question might be far too broad for a succinct answer here, I wonder if someone can point me in the right direction.</p>
  
  <p>Is there functionality built into either PHP or jquery to do this?  Will I need additional libraries or resources or anything?</p>
