We needed to do this too. Luckily, it’s an easy fix ?? .
In flshow.php, head down to line 731. You should see:
$slide_show->appendChild( $photo );
Before it, simply add:
$photo->setAttribute('target', '_self');
That section should then look like:
if( !empty( $flShow_link ) ) {
$photo->setAttribute( 'href', $flShow_link );
}
$photo->setAttribute('target', '_self');
$slide_show->appendChild( $photo );
Note that this is a quick fix and will cause *all* of your links to open in the same window.
Best regards,
