You can change the name in the array in this file:
/wp-content/plugins/bogo/includes/functions.php
I was able to workaround this issue by creating a new gallery.
Next, I copied the images across from the old gallery to the new gallery.
Then, I updated the gallery ID number in the page/post used.
I had only a few galleries so didn’t take too long to do.
You can add links to each of the images in:
Gallery > Manage Gallery > Alt & Title Text field (insert URL here)
