Images in CodeIgniter, how to?

Yeah. But I doubt if it will you any good. You need to get the file contents from the image and echo them in your view, where they will be visible for everyone to see an grab. So, as long as you show them in an public accessible environment, placing images outside the webroot does not seem to make much sense.

Having said that:
Place images anywhere outside the root folder, e.g. ../images. Then, from your view, call a page that gets the contents of that file and echoes it (make sure you set the right content headers or the browser will not display it as an image!)

Code:

// Get data from file
$data = file_get_contents($filepath);

// Set mime type (image/png, image/gif, image/jpeg)
echo header('Content-Type: image/' . $mime_type);

// Echo file
echo $data;

This means every bit in every image is processed by your server's CPU, it could become quite a memory hog!
