    <button type='button' class='close' data-dismiss='alert' aria-label='Close'><span aria-hidden='true'>×</span></button></div>";
    header("Location: ./");
}

Answer 1

It can be something of configuration, when going to check which type of image can go up must tbm put the maximum size allowed,have a chunk in codeigniter that would be:

$config['upload_path'] = './public/images/noiva';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 2000;
$config['max_width'] = 1024;
$config['max_heigth'] = 768;

You would have to see how it would look in PHP root.

Answer 2

Well it’s probably a setup on your php.ini

Search your php.ini for these settings:

post_max_size
upload_max_filesize

And change them to a higher number, after changing, try again to insert an image.
