Tiled gallery not displaying

Images are not displaying on one page only: https://burleighheadsuniting.org.au/2014/11/11/bunnings-sausage-sizzle/ Initially the images showed up – now I only have little symbols indicating where they should be. You are still able to click on them to display full size.

We did have an issue with uploading content to WordPress this week (reaching our data capacity – unable to upload). Might this have affected it?

Thank you.
