Masonry Gallery: Opening some links in NEW WINDOW & some in SAME WINDOW

Hi, I’m using the Masonry Gallery for different parts of my website however I need the gallery to open up some links in a new window and some in the same window.

For example on my home page the gallery opens a link in the same window however when I use the gallery on other pages I want the links to open in a new window/tab. I initially searched the forum and found the following code which makes the links to open in a new window however this makes the entire Masonry Gallery to open all links in a new window regardless of what page I use it in:

==================================
function add_custom_script(){
?>
<script>
jQuery(window).load(function(){
jQuery(‘.av-masonry a’).each(function(){
jQuery(this).attr(‘target’, ‘_blank’);
});
});
</script>
<?php
}
add_action(‘wp_footer’, ‘add_custom_script’);
==================================

I would like to know if there is any solution to have either one of those options. I have included the sample pages in the PRIVATE CONTENT. I would appreciate if you guys can help me out regarding this issue.

Thanks again!
