Why would you want to retrieve the image directly from the cache folder? You
are already caching the response itself, so you can simply retrieve it.
Something to do would be like the following:
If Cache::set('latex_response') {
$response= Cache::get('latex_response');
}
else {
$request = new RemoteRequest( $generated_image );
$request->execute();
$response = $request->get_response_body();
}
// User the response variable here to construct the img tag... and proceed.
