Thanks Alex for quick reply.
I I've double checked all that I can. The wierld thing is the rrd file is 
being updated but not the image files(.png images). I've verified by 
directiories, my cfg files and my cgi files. I can even run them on the web 
..can see call my descriptions, the date/time when statistics were updated 
but No graphs Getting that  (Error:Cannot create graph)
It was working fine before and I didn't change anything ...same settings, 
same directories + I don't want to loose all the data I had before.

I know it's probably something small I'm missing somewhere.
Any more input would be great.
