from the output of curl_exec extract the url:

/NetPerfMon/Chart.asp?Chart=AVGRTLOSS&NetObject=N:4&Period=Today&SampleSize=30M&ReBuild=TRUE&FontSize=Medium&Width=640&Height=0

then make another call with curl_exec() using that url
the data you get back should be the image, save it to disk.


....thats basically what you browser would do.

or just use that url iso the url that you are currently
using (the one that outputs a page with (only!?) an img tag in it.)
