I didn't have enough images on my board to require page navigation until now, so I couldn't see the bug some of you had noticed.
But I do now.
Anyway I had a look in an old backup and found the required templates.
As they are no longer in use I hope it's not a problem posting the code here.
numbernav
PHP Code:
[ $firstpage_atag<<$endfirstprevtag $prevpage_atag<$endfirstprevtag $pagenumbers $nextpage_atag>$endlastnexttag $lastpage_atag>>$endlastnexttag ]
numbernav_pages
PHP Code:
$numbernav_atag$curpage$endpagetag
I have tested them and they are working fine.
