I'm an idiot, in that pointing this to a requestAction is obviously not going to work. I figured that out soon enough, and have the src attribute pointing at the controller's action, which calls the component method to create the PNG image. I'm still getting the same error, though.
I used wget to grab the image directly and looked inside it, which revealed the Cake debug messages inside. I set debug to 0 and tried again but still no luck. The file utility says that it's data but does not recognise it as a PNG. Though, this works fine on the old site on the same server, using the same PEAR packages. The controller method currently has: $this->layout = null; $this->autoLayout = false; $this->autoRender = false; // DB code ... $this->Graphing->makeLineGraph($data); makeLineGraph() outputs the PNG file with $Graph->done(), which takes care of the headers and calls ImagePng(). The response headers when requesting the image directly are: Date: Wed, 05 Mar 2008 19:17:27 GMT Server: Apache/2.2.6 (Fedora) X-Powered-By: PHP/5.2.4 P3P: CP="NOI ADM DEV PSAi COM NAV OUR OTRo STP IND DEM" Expires: Tue, 2 Jul 1974 17:41:00 GMT Last-Modified: Wed, 05 Mar 2008 19:17:28 GMT Cache-Control: no-cache, must-revalidate Pragma: no-cache content-disposition: inline; filename = "index.png" Connection: close Transfer-Encoding: chunked Content-Type: image/png 200 OK Is there something else I need to do in the controller with respect to the view? That is, I'd like to emulate requestAction(), where there is NO view or layout dealt with.
