Re: Displaying images using MediaView based Controller - Help!

If you're going to use a Base64 data URI you'll need to encode the output.

Are you trying to do this because the images are above webroot?

Also, there's a problem with this line:

header('Content-type: $type');

Where does $type come from? Anyway, I think MediaView handles that header.
