I don't know what you plan to do, but only for displaying the image you=20
don't need php nor curl nor the header() thing. Display the image with a=20
html page including a image:
<img src=3D'http://nagtst01/nagios/cgi-bin/perfchart.png?host=3Doma3a001&..=
=2E'>

If you plan to cache images or want to copy the images automatically, then=
=20
it would be best to call the binary perfchart.png via cron or commandline=
=20
and write the output in a file:

Set the query string as apache would do:
  export QUERY_STRING=3D"host=3Dbvba1&service=3DCPU+Load&metric=3Dload15&se=
lect_line=3D1&s_val=3D1&s_smo=3D0&s_war=3D1&s_cri=3D1&s_sta=3D1&g_sigma=3D1=
4.000000&timeperiod=3Dr&reltime=3D00%3A00&reldays=3D1"

execute the cgi:
  ./perfchart.png > /tmp/test.png

This file then includes the http header. Usually 3 lines. These can be=20
stripped with some shell script:

L=3D`wc -l /tmp/test.png|awk '{print $1}'`
tail -n $((L-2)) /tmp/test.png > /tmp/test_stripped.png

Probably there will be one time a option that surpresses the header=20
output.
