My blog is hosted on my own server that, to my knowledge, is configured correctly.
When I access it on the server itself, it all works (including images). When I try to access it on a different computer, any images don't work.
This is not a permissions problem, all folders are 755, and all files 644. I have triple-checked this, and as far as the server is concerned I can see no reason why it would treat the contents of the themes folder different from the others.
This issue seems to be only with the themes as other folders seem to be unaffected (/wp-images/get-firefox.png works, for example).
This doesn't seem to be an issue with WordPress, but I thought I'd ask on the off chance... any ideas anyone may have would be greatly appreciated.
