Going from a zoom in picture >> open a new tab

Infant coder here, used a template for my site where I wanted to showcase my work. The problem is the UX is really bad; in my portfolio section, I want the users to click on one of the images so it opens a new tab, instead of zoom in on a photo. I’ve tried to modify the JS and create a new function new tab but when I do that it stops all the other scrips on the page and no info shows up. Maybe someone on here can help? Here’s the link to the template I’ve used: https://templateflip.com/templates/super-folio/

here’s the part of the code that’s tripping me up:

 /**
   * Big Picture Popup for Photo Gallary
   */
   document.querySelectorAll(".bp-gallery a").forEach((function(e) {
    var caption = e.querySelector('figcaption')
    var img = e.querySelector('img')
    // set the link present on the item to the caption in full view
    img.dataset.caption = '<a class="link-light" target="_blank" href="' + e.href + '">' + caption.innerHTML + '</a>';
    window.console.log(caption, img)
     e.addEventListener("click", (function(t){
       t.preventDefault();
       BigPicture({
        el: t.target,
        gallery: '.bp-gallery',
      })
     })
    )
  }))

When I changed it, I did:

 /**
   * Big Picture Popup for Photo Gallary
   */
   document.querySelectorAll(".bp-gallery a").forEach((function(e) {
    var caption = e.querySelector('figcaption')
    var img = e.querySelector('img')
    function NewTab() {
        window.open(
          "a", "_blank");
    )
  }))

Which worked, but made all of the other text on the page disappear or unresponsive.

Any help you could provide would be great!
