I'm trying to put some graphics on a web page and at my prototype at the computer it's all working fine at the localhost. But now I uploaded the files to a server and I'm having a problem to plot some graphics. In my computer they are plotted, but on the server they are not.
I'm getting this error
Fatal error: Call to undefined function ImageCreate() in /home/t1g01/phplot.php on line 248
$this->img = ImageCreate($this->image_width, $this->image_height);
This means your installation of php doesn't have the gd library installed/enabled.
