I've got a image made in GD Lib
I want to draw a line on there as it's a graph however the draw line function has no width. how can I draw a line which is 3-4pixels in width?
My initial thought would be to either use [man]imagefilledrectangle/man or [man]imagefilledpolygon/man.
There is also [man]imagesetthickness[/man], which apparently is for setting the thickness of lines.
