[PHP] problems creating a png image from an array{HELP}

2001-01-18 Thread Nikos Tahos 

I have a txt file as input.This file has the coordinates for a gas
network.With php I am creating an array with the above coordinates and then
I create from the array the image from the network.When the txt file is
>21Kb there is no image, else all works perfect{with a smaller txt file).I
am using php4,apache(sometimes my system hangs with this server) or OMNI
httpd(works fine).
If anybody know sth PLEASE HELP ME
I am newbie in php programming
