I just installed this plugin and it works fine, but the standard search link in SUB_MENU was not replaced in any theme installed, I had to do it manually.
Italian translation attached.
A short mod for a complete translation:
OPEN
lang/english.php
FIND (line 1632)
$lang_adv_opts = array(
'title' => 'Title', //cpg1.4
'caption' => 'Caption', //cpg1.4
'keywords' => 'Keywords', //cpg1.4
'owner_name' => 'Owner name', //cpg1.4
'filename' => 'Filename', //cpg1.4
AFTER, ADD
'alb_title' => 'Album Title', //Search Album Plugin
'alb_desc' => 'Album Description', //Search Album Plugin
OPEN
lang/italian.php
