Avatars plugin upload gives fatal error

WordPressMU v 2.7.1
all files are in the correct directories. .htaccess file has been overwritten with it's new line (file attached)
When users attempt to upload a graphic for an avatar they get this error:

Fatal error: Call to undefined function: imagecreatefromjpeg() in /Library/WebServer/Documents/wp-content/mu-plugins/avatars.php on line 566

    First off, upgrade WPMU! You really can't delay those updates or your site will get hacked. It's one thing to be lazy with your personal wordpress blog, but when others are depending on you for their blogs to be secure you don't have an excuse.

    Fatal error: Call to undefined function: imagecreatefromjpeg()

    Most likely you need to install the GD image extension in PHP.
