Image links suddenly broken

Hi. I’ve had this site running fine for a few weeks: https://www.theatreclub.ie , but noticed today that all of the image links suddenly broke. They’re now all linking to localhost paths. Strange since I didn’t change anything and everything was fine before.

Permalink settings are all correct, as is the site URL. So I’m unsure how to go about fixing this.

(Any images that are showing are the images with hand-coded urls).

I’d appreciate any help on this.
