Is there a way to have a Codeigniter controller return an image?

Question

I was wondering if there was a way for a controller to, instead of returning a string, or a view, return an image (be it JPG, PNG etc). For example, instead of ending with a $t

Answer 1

If it fits your use case, simply redirecting to it is just fine. For example, tracking using images would be like:

// Do your logic here

redirect($image_path); // Or PHP's header location function

No need to change headers. Your use case may not fit this, but someone might find this useful ^_^
