Hi KrisC - I know this thread is several months old, but can you please let me know how you fixed this image block issue? I'm having it only happen on the landing page and it worked perfectly for over 2 years, then I went to switch the .png graphic to promote an event and now the image block says it's there, I can see it in editor mode, but viewer mode is an empty space. Even links work when I link the invisible image.
Thanks!
