[Plugin: NextGen Gallery]

I am using the latest NextGen Gallery version and I want to replace the pagination’s “Next” and “Previous” button symbols from black arrows (left and right arrows) to angle quotes (raquo and laquo, respectively).

I managed to change the code in the plug-in folder’s pagination file (“mixin.nextgen_basic_pagination.php”)

from

$prev_symbol = apply_filters('ngg_prev_symbol', '◀');
  $next_symbol = apply_filters('ngg_next_symbol', '▶');

to

$prev_symbol = apply_filters('ngg_prev_symbol', '«');
  $next_symbol = apply_filters('ngg_next_symbol', '»');

The page where my gallery is displayed successfully changed the black right arrow into a raquo upon first click. But when you click for the next pagination number, the buttons go back to their black arrow forms.

Also, I’ve noticed the url path hierarchy changes when you click the gallery itself. It changes

from

localhost/migsmarbella.com/?page_id=31

(page id for the page where the gallery is displayed)

to

http://localhost/migsmarbella.com/index.php/migsmarbella.com/nggallery/page/2?page_id=31/

Can you help me change the “next” and “previous” buttons? And would you also explain why the changed url path became like this? Thanks
