Simply go to your theme folder:
YourSite.com/wp-content/themes/NameOfYourTheme
Most likely your pagination shows in Categories, Archives, so you need category.php and archive.php files (look for details https://codex.www.ads-software.com/Template_Hierarchy)

There you need to find <?php if( function_exists( ‘wp_pagenavi’ ) ) { wp_pagenavi(); } ?> or something like this and replace this part higher in code where you want to appear pagination. I think you can duplicate it to have pagination on top and in the bottom.

I am sorry in previous message i added html tags in code.

and change it to:

// clean mode if needed
    $mode = ( preg_match('/(web20|watermark|crop)/i', $mode) ) ? $mode : '';

in nggfunctions.php in function nggSinglePicture find next line:

// clean mode if needed
    $mode = ( preg_match('/(web20|watermark)/i', $mode) ) ? $mode : '';

and change it to:

// clean mode if needed
    $mode = ( preg_match('/(web20|watermark<strong>|crop</strong>)/i', $mode) ) ? $mode : '';

then use [singlepic id=165 w=320 h=240 mode=crop float=none]
