Hi,
I noticed that when rrdtool didn't create an image caused by some error
you get a broken image....
I've written a small patch which checks for rrdtool error's and if found
it will send a transparant 1 pixel gif instead.
Maybe instead of a transparant pixel we can greate a nice N/A image or
something but for now this will do the job.
This patch is against the latest stable release.
With kind regards,
Jeroen Nijhof
