I think we are bumping up against some type of limit due to the amount of images that need to be loaded in threads like this. It's sometimes a couple hundred images+ to pull up a thread and I'm not sure which limit it might be. There are a few possible culprits (and of course increasing those limits could have other impacts). I noticed several images missing when I load the page, but wonder if people on slower net see a lower % of them loading, as that might give us some idea what needs to be changed.
