The problem is the same, but I obviously had to remove the code you just quoted so that the images appear. The downside is that there are no Expires set in headers. Not sure why you say the situation is different.
The general route to take here is to first create a simple setup that works without all the extra gimmicks that noone really needs. Then, once the setup works, add the gimmicks step by step.
