Image Lightbox to include text

Hi! I was wondering if someone could walk me through some code (if there is some) that allows me to click on an image (someones headshot) and the lightbox of it pops up with a bio description of them? Let me know if thats possible. Also I am still learning code so the simpler the instruction is the better haha. Thanks!

You can use Lightbox Plugin to achieve this

1. Create 6 bio pages

2. Insert Lightbox
