conditional image generation problem

Hi, I have a problem with conditional image generation. If I generate an image without any conditional statments, then everything works fine. But if i introduce conditional statment, then no image is generated in either case of the condition. Has anyone dealt with this dilema before? Thanks in advance, alex P.S. I am generating a hit-counter image. The set-up is very basic: if admin looks at the page, then image should be generated and displayed if anyone else loads the page, no image should be generated. my code goes smth like this: <?php if (! fromOffice() ) { $image = ImageCreate(1,1); $navyblue = ImageColorAllocate($image, 0, 0, 0); ImageFilledRectangle($image, 0, 0, 1, 1, $navyblue); } else { $image = ImageCreate(125, 150); //... } header("Content-Type: image/png"); header("Content-Disposition: inline; filename=counter.php"); ImagePng($image); //have to destroy the image, otherwise will starve web-server's memory ImageDestroy($image); ?>
