GD Library

GD is an open source code library for the dynamic creation of images by programmers. GD creates PNG, JPEG and GIF images, among other formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly. While not restricted to use on the web, the most common applications of GD involve web site development.

More info and download the GD Library follow the links,


Here I posted the code to check whether the GD Library added in your server properly enabled or not.

echo ‘<div style=”margin: 10px;”>’;

echo ‘<p style=”color: #444444; font-size: 130%;”>GD is ‘;

if (function_exists(“gd_info”)) {

 echo ‘<span style=”color: #00AA00; font-weight: bold;”>supported</span> by your server!</p>’;

 $gd = gd_info();
 foreach ($gd as $k => $v) {

  echo ‘<div style=”width: 340px; border-bottom: 1px solid #DDDDDD; padding: 2px;”>’;
  echo ‘<span style=”float: left;width: 300px;”>’ . $k . ‘</span> ‘;

  if ($v)
   echo ‘<span style=”color: #00AA00; font-weight: bold;”>Yes</span>’;
   echo ‘<span style=”color: #EE0000; font-weight: bold;”>No</span>’;

  echo ‘<div style=”clear:both;”><!– –></div></div>’;

} else {

 echo ‘<span style=”color: #EE0000; font-weight: bold;”>not supported</span> by your server!</p>’;


echo ‘<p>by <a href=””></a></p>’;

echo ‘</div>’;

Here the above code will display status like this,

    … can you also tell me how the PHP activation code for a such GD Library generated security code/image usually looks like and most of all how to tweek it to display what i want rather than what a free script has by default (that is to hard to read)???
