Image caching with Codeigniter

Question

How do you cache image/s with Codeigniter? The images are not being stored in my database.

Thanks!

Answer 1

put this in your controller if you're talking about images being stored in your database:

$this->output->cache(10);

Answer 2

You can cache the images with mod_expires and Apache. It does not depend on CodeIgniter, it is rather a general solution.
