 * Hello,
 * I use IIS server and I got this error:
 * > There is something about the site configuration that worries me:There seems
   > to be no PHP library for manipulating images.
   >  You probably won’t be able to
   > optimize images with this setup.
 * What library do I have to install for this plugin?

 * To manipulate wordpress images use the php Gd libraries or Imagick ([https://developer.wordpress.org/reference/classes/wp_image_editor/](https://developer.wordpress.org/reference/classes/wp_image_editor/))
 * To activate the php GD library, just go to the php.ini file and uncomment
    extension
   =gd
 * ([https://www.php.net/manual/en/image.installation.php](https://www.php.net/manual/en/image.installation.php))
 * Then you have to restart the server to apply the changes.
    You will need the 
   GD library not only to run my plugin, but also to run other wordpress settings
   such as thumbmails and the ability to manipulate images.
 * Without a graphics library wordpress works, unfortunately my plugin does not.
