Lightbox not loading properly

Site URL: https://www.imyeg.com/council-of-founders

Hello!

I have used this code to create lightboxes on this page for people's bios:

<link href="//cdn.rawgit.com/noelboss/featherlight/1.4.0/release/featherlight.min.css" type="text/css" rel="stylesheet" />   <script src="//code.jquery.com/jquery-latest.js"></script> <script src="//cdn.rawgit.com/noelboss/featherlight/1.4.0/release/featherlight.min.js" type="text/javascript" charset="utf-8"></script></link>

However, it often takes a long time for the content in the lightbox to load when clicking on the photos / names of the individuals (just showing a white box with no content in it). After clicking out of the box and re-opening it a few times, the content sometimes loads, but it is not ideal. Here is an example: 

I was wondering if there is a way to avoid this?

Thank you!

It loads fine here. Which device/browser do you use?

I use Chrome. Multiple users have encountered this error, and it usually occurs when one clicks immediately on one of the images / names to open a lightbox. It seems like the issue might be with the loading time?

Thank you!
