Displaying EXIF information in NGG Pro

Hi,

I try to get EXIF information displayed. I had that working in the non-pro version, but the pro version is different. I located the code in class.nextgen_pro_lightbox_controller.php:

foreach ($images as $image) {
                        $retval[] = array(
                            'image'       => $storage->get_image_url($image),
                            'title'       => strip_tags($image->alttext),
                            'description' => strip_tags($image->description),

                            'image_id'    => $image->{$image->id_field},
                            'thumb'       => $storage->get_image_url($image, 'thumb')
                        );
                    }

I tried to add something here:

'description' => $image->description. '? ' . utf8_decode($image->meta_data['copyright']) . ', ' . $image->meta_data['created_timestamp'] .' @ '. $image->meta_data[focal_length]. ' - '.$image->meta_data[shutter_speed].', ' . $image->meta_data[aperture] .', ISO '.$image->meta_data[iso],

But this did not work.

Any suggestions would be most welcome.

Thanks

Stefan

PS: Suggestions how to make this update save would be very welcome too.
