First off, yes I have both of those blogs in my blog surfer and their images are showing just fine.
With IE8, try switching to compatibility mode. See this page and click on the "compatibility view" link to the left and it will show you how to do it: http://www.microsoft.com/windows/internet-explorer/features/easier.aspx .
IE's market share continues to dwindle and with their refusal to build their browser in to be compliant with established web standards, they not only become less relevant by the day, but are irritating web designers to no end. Web designers are getting very tired of having to jump through convoluted hoops just to accommodate IE.
Where IE enjoyed an 85% browser market share at the beginning of 2003 - when Mozilla (later to become Firefox) introduced their browser - that is now down under 40%. At some point, designers will just turn their back on IE entirely. Microsoft will then be forced to either build a web compliant browser, or simply fade into irrelevance.
