+<p>
+<br />
+An image library is required by Tidypics to perform various manipulations: resizing on upload, watermarking, rotation, and cropping.
+There are three image library options with Tidypics: PHP extension <a href="http://www.php.net/manual/en/book.image.php">GD</a>, 
+<a href="http://www.imagemagick.org/">ImageMagick</a> called via a system call, and the PHP extension 
+<a href="http://pecl.php.net/package/imagick/">imagick</a>. GD is the most common of the three on hosted servers but suffers 
+from serious memory usage problems when resizing photos. If you have access to ImageMagick (whether through system calls or the
+PHP extension), we recommend that you use that.
+</p><p>
+<h3>Testing ImageMagick Commandline</h3>
+To use the ImageMagick executables, PHP must be configured to allow calls to exec(). You can check our 
+<a href="<?php echo $CONFIG->wwwroot . 'mod/tidypics/pages/server_analysis.php'; ?>">server analysis page</a> to find out the 
+configuration of your server. Next, you need to determine the path to ImageMagick on your server. Your hosting service should 
+be able to provide this to you. You can test if the location is correct below. If successful, it should display the version of 
+ImageMagick installed on your server.
