The images are meant to be lazy loaded - as in the page loads first, and then the images load. I'm wondering if there's a conflict with an Adblock rule.
Yea I do run Adblok but have also tried it switched off and in IE 7 which has no add ons, same issue. Not that I'm complaining as I tend to read the write ups anyway, plus the page tends to load a little faster. :)
As an update IE7 now loads home page fully including pics but individual article pics still have trouble loading. But not bothered by that as I don't use IE. :)
