Images have disappeared!

Everything was working fine yesterday. Today I go in and no photos are attached to the galleries, https://sarasotalibraryfoundation.org/programs/photos/ … this site is part of a Multisite.

I can see the images in the FTP site ans they’re in the correct location but I am unsure what is causing the issue and how to fix it.

Any help is appreciated.
