Sounds like there other non-image content being pushed to the browser. I got something similar when sending PDF's to the browser.
Check the bottom of your controller for any spaces after the ?> Also if you open the image directly then view its source, you should be able to see the extra non-image content. If not you could try changing the header('Content-type: image/gif'); to text for a run and see if you can spot the non-image content.

I would need to reset the header's content type but I'm still having problems (in browser error returned below). I've included some comments on various things I tried. My code looks like this: public function somethingAction(){ //ob_start(); $this->_helper->viewRenderer->setNoRender(); $this->_helper->layout->disableLayout(); if($this->_generate('play.html',$data)){ $this->_success(); }else{ $this->_failure(); //echo "failure<br/>"; } } private function _success(){ $file_name = "/data/sites/site/www/docs/fadmin/images/ok.gif"; if(ob_get_length()){ ob_end_flush(); exit; } /* $this->_response->setHeader('Content-type', 'image/gif'); $this->_response->setHeader('Cache-Control', 'no-cache'); */ header('Content-type: image/gif'); header("Cache-control: private, no-cache"); header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); # Past date header("Pragma: no-cache"); echo fread(fopen($file_name, 'rb'), filesize($file_name)); /* ob_end_flush(); $data = file_get_contents($file_name); $this->_response->setBody($data); */ ob_end_flush(); } The error I get in the browser is: The image "http://jt.agpublishdev.shockwave.com/fadmin/app/generator/play-with-friends /" cannot be displayed, because it contains errors. <http://jt.agpublishdev.shockwave.com/fadmin/app/generator/play-with-friends /> Any help with this would be greatlly appreciated. thanks, jonathan
