Hey,
Can you link to the actual fail map instead of a screenshot so I/we can look at this in Firebug ourselves? I'm pretty sure /something/ is going wrong with image URL remapping here, but it's hard to figure out what unless I can see it fail in my browser.
Sure, the issue can be seen here: http://wiki.bn2vs.com/OpenLayers_map_with_RL
Cheers
