Hi there!

Sorry for your experience.

Would you please give me your admin access to check the issue for you? Please keep a full site backup before giving the access.

Best Regards

Hi Nicole,

It's becuase you used extra extension/script that moved all those photos to cdn.optipic.io server. Here is evidence from your site source code:

Notice! By default Gallery use images loaded from that same server as website is. So it's not our issue this time.

Check in extensions that you have installed as extra one for site (images) optimization, find CDN option, and turn off & recheck. Also talk with plugin developer about presumptive reasons of this behavior.
