title: send uiimage to a server
body: <p>Until now I send <code>strings</code> to a server with this method:</p>
  
  <pre><code>NSString *reqURL = [NSString stringWithFormat:];
  reqURL = [reqURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
  NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:reqURL]];
  NSURLResponse *resp = nil;
  NSError *err = nil;
  [NSURLConnection sendSynchronousRequest: theRequest returningResponse: &amp;resp error: &amp;err];
  </code></pre>
  
  <p>and I want to know if there is a possible to send an <code>UIImage</code> to server.</p>
