Hi,
So I've had this working perfectly. The images are stored above the
webroot
/app
/uploads
img01.jpg
The controller has an action which accepts the file name of the image,
adds some HTTP headers and outputs the image contents using
readfile().
Now I can't be 100% sure but it seemed to start happening after I
enabled Cake's caching feature. However, I've since disabled it but
the problem remains.
I've spent a few hours debugging this and here is what I've come up
with so far:
I can get the images to display correctly in my browser with a simple
test script (no Cake) containing the following code:
$file = 'path/to/img001.jpg';
header('Content-Type: image/jpg');
header('Content-Length: ' . filesize($file));
readfile($file);
So to me that rules out Apache or PHP as potential culprits.
========================================
The HTTP headers from my test script

----------------------------------------------------------
I've tried removing the P3P: CP="NOI ADM DEV PSAi COM NAV OUR OTRo STP
IND DEM" but that didn't solve the problem.
Also, here a stripped version of the code in the controller's
displayFile() action:
function displayFile($id, $file_name, $type=null) {
Configure::write('debug', 0);
session_destroy();
$this->layout = '';
header('Content-Type: image/jpg');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
I'm hoping someone can shed some light...
