It's quite recent: since last week, some of the images from my tiled galleries are not loading anymore. Images not loading are random as the image order changes every time you reload the gallery.
If I click on the icon representing the image, the image will actually load (I use Fancybox).
I already tried disabling all plugins (including Fancybox) but it doesn't help. Any idea what could be wrong? Too many pictures in my pages? Timeout somewhere?
