None of the images in this thread have displayed for about 48 hours now? No changes on my end. Anyone else having problems? 
it's the DDOS protection, the first time you load bitcointalk.org, you get no reply. If you reload, it does load all the next requests in a certain timeframe.
The same applies to the images, just open a broken image in a new tab, reload it and it will load. From then on, all HTML requests will also load the images
