Creating Images using separate PHP files.

I have crated a class to generate a graph. If I include the class and the function calls in one file, it displays the image correctly. If I put the function calls in a separate file and call the class, a header error is displayed. I tried moving the header call to the file w/the functions, but it only displays a blank page. Things basically look like this: ------ <? /* Header("Content-type: image/png"); I tried adding this here but it generates header errors */ require('graphclass.php'); $graph = new GraphMe("Graph Title",500); $graph->addbar("one",1); $graph->addbar("two",2); $graph->addbar("three",3); $graph->addbar("four",4); $graph->drawgraph(); ?> ------ And here is basically what happens when the $graph->drawgraph function is called: ------ Header("Content-type: image/png"); $image = imagecreate($this->width(),$this->height()); ImagePng($image); ImageDestroy($image); ------ I assume that the first file needs to state that an image is coming and not a html file, but when I add the Header call to the first function it seems to think my class is printing to stdout. Any help would be wonderful! thanks, -- Matt Glaves Systems Engineer Pinnacle Online www.pinn.net
