How do I install the GD library on my Droplet?
I have a Droplet running Ubuntu 14.04. I tried to install the GD library using
sudo apt-get install php5-gd and it seemed to install fine. I restarted the Apache2 service, but my image upload script still gives this error:
Call to undefined function imagecreatefrompng()
Are there any additional steps I need to take before the GD library is available to my PHP scripts?
