title: calling another php file using <img> tag
body: <p>image.html -
  <code>&lt;img src="showImage.php?id=44"/&gt;</code>  &lt;-- this is the code I'm trying to make work.</p>
  
  <p>showImage.php -
  <code>&lt;?php  echo ("showImage.php called");   ?&gt;</code> &lt;-- this is the php file I'm trying to call.</p>
  
  <p>The problem is.. img tag is not calling 'showImage.php' to print out "showImage.php called.". Instead, it tries to display showImage.php file as an image :( ... and doesn't display what it's supposed to. Am I doing something wrong here?</p>
  
  <p>*Note: id=44 will be used for something else... not a big concern here.</p>
  
  <p>Thank you.</p>
