[Plugin: NextGEN Gallery] Code for Singlepic link in _blank

Am using SinglePic shortcode with Nextgen to manage banner links on some pages. Need to have most of them (but not all) open in a new window with “target=_blank”
What I did is the following below (sorry if not perfectly clear at 4am) and it seems to work. This adds a shortcode for singlepic of “target=” Am I missing anything with this? Any way to have this implemented in a future version of Nextgen as am sure it can be useful for others and a pain to edit after updates?
My favorite plugin!

/lib/shortcodes

Before line 350
add:
           'target'      => ''

Around line 357
change line to: (adds the $target)

$out = nggSinglePicture($id, $w, $h, $mode, $float, $template, $content, $link, $target);

------------------------------------------
/view/singlepic.php

At line 43
Change to read: (Insert: target="<?php echo $image->target ?>")

<a href="<?php echo $image->imageURL ?>" target="<?php echo $image->target ?>" title="<?php echo $image->linktitle ?>" <?php echo $image->thumbcode ?> >

-------------------------------------------
/nggfunctions.php

After line 1631:
Insert:

    $picture->target = $target;
