All the pictures (or php file producing the pic) in my cacti installation are being called by the full URL.The wierd thing is that image files in a web page aren't required to include the full URL, the browser knows that it comes from the current page. This actually works fine in my IE and Firefox. More than likely is working fine in yours in most situations.
The picture (well php file generating the pic) is already in the current working directory. Correct me if i'm wrong but wouldn't it either be the full URL or just the calling the current file work? If /cacti/ is already the current working direcotory, you specify the directory again, would it not make the server try to pull the file from 'http://server/cacti/cacti/blah.php'? (altho i have to admit, you'd see that in the html source, but I didn't get that either)
I'm using IE (6.0) at the moment, but the apache server is what is locking up. I can test this by pulling the page on one PC and attempting to load a plain old test HTML file on another PC and the server wont respond or indicate a connection attempt. I can also let either PC 'sit' and finally time out, and navigate other websites just fine, but I can never get back to my server after (so it's not a browser crash). I'll try to use firefox, but (for reasons I cannot explain) it is not allowed on our network and switching is not an option for us.
I hate to be the squeeky wheel but this plugin is prolly the best feature to ever be added to cacti. Thank you for the hard work you put into it.
