Can't upload logo

[cpthomp]

Hello,

I'm trying to upload a png logo for the banner and whenever I hit save, I get this: Server Error: 500 (Internal Server Error). Is this a known bug or is there something I can do on my side?

In the error logs:
[2015-04-27 15:27:25] production.ERROR: exception 'Intervention\Image\Exception\NotSupportedException' with message 'GD Library extension not available with this PHP installation.' in /var/www/snipeit/vendor/intervention/image/src/Intervention/Image/Gd/Driver.php:18
