I added pages with audio samples of my CD and a photo to my existing website in iWeb. I published the entire site but the added pages are not there. I tried emptying the cache, reloading , etc. with no luck. I am with an FTP not MobileMe. However, I have no problem revising the existing site and publishing revisions.
What version of iLife are you using?
Which browser and are you uploading to your site from within iWeb or through a 3rd party app?
What do you mean:
"However, I have no problem revising the existing site and publishing revisions."
What kind of revisions work?
