image processor and sessions - El Forum - 10-06-2011

[eluser]quasiperfect[/eluser]
hi

i have a controller that manages all my images
the idea is that i want to show some images based on session variables

i call the controller in my html like this

Code:
<img src="http://site/image_processor/parameter/parameter/">

my controller logic is like this
make some verifications if user is ok then show image like this

Code:
$im = @imagecreatefromjpeg($image);

if(!$im)

{

   $this->_img_error($errorcode);

}

else

{

    header("Content-type: image/jpg");

    imagejpeg($im);

    imagedestroy($im);

}

the function _img_error generates a image with a text containing the error so i always output a image

the problem is that i get a lot of errors in my logs because the headers are already sent
when the session lib sets the cookie

any idea on how to solve this ?
