Bug Report - Images Not Found
UPDATE 12/31/2013 - This Bug Seems to have disappeared and no more image loading problems are occuring. Google Sites is currently experiencing an issue where images, whether background images, logos, page images, icons, etc, are not being found and result in a broken image link. At this point it is very sporadic and images may appear, reappear and be generally glitchy. It has been reported to Top Contributors on the Google Sites Help Forum and consequently has been escalated to Google Sites team representatives. Ya, it's a problem.
