Right, I got that part - My original question still remains. Are the  
server logs returning a 200 on the requests which don't actually show  
images, or are they displaying a 304?

For example -
192.168.1.50 - - [18/Jan/2009:14:02:06 -0500] "GET /images/bggrad.jpg  
HTTP/1.1" 200 415 "http://narco.noctum.net/style.css" "Mozilla/5.0  
(X11; U; Linux i686; en-US; rv:1.9.0.5) Gecko/2008121621 Ubuntu/8.04  
(hardy) Firefox/2.0.0.11" "-"
192.168.1.50 - - [18/Jan/2009:14:04:16 -0500] "GET /images/bgbody.jpg  
HTTP/1.1" 304 - "http://narco.noctum.net/style.css" "Mozilla/5.0 (X11;  
U; Linux i686; en-US; rv:1.9.0.5  Gecko/2008121621 Ubuntu/8.04 (hardy)  
Firefox/2.0.0.11" "-"

In the first case, it tells me that it returned a 200, and sent 415  
bytes, and in the second, it was cached and returned a 304. I have  
seen instances of a webserver returning a 200 result code, but  
transferring 0 bytes, which is why I'm curious if that's the case here.

Well that means it's likely not an apache configuration problem, and I  
doubt it's hardware as well. So it's probably something in the OS.

Usually when I see weird crap like this, it's a permissions issue, and  
usually after I've already started tearing my hair out because I  
assumed that permissions couldn't possibly be the problem! :) I've  
also seen some strange behavior come about as the result of funky  
rewrite rules.

But check the apache error log as well.
