AuthImage/Veriword Problem

I don’t seem to be able to get authimage working. I’ve installed it just as said, but can’t get it to see the image. I noticed in the Veriword include, there is a file called sample.php. On my server it has the same exact problem of no image.

Looking on other server that it works on (for example: https://ink.bur.st/wp-content/plugins/authi…inc/sample.php ) that same file works. Which leads me to believe that either my host is missing something for Veriword to work, or I’m doing something really wrong.

I’ve noticed something else. If I try to look at the image itself, I get an error:

Fatal error: Call to undefined function: imagettfbbox() in …./wp-content/plugins/authimage-inc/class.wordart.php on line 128

Here is my phpinfo:

Any help would really be appreciated.
