Hi Mike, yes I need to know what browser your using and a thread number or two where you cannot see the pictures since I suspect its not all threads just a small number of them where the coding had been changed.
OK I found one of your threads in the archives that the pictures weren't showing up in IE and fixed the bug, which probably fixed everything. Let me know. (be sure to hit refresh on any only thread in the archives that you cannot see the pictures to reload the page).
