On the photo slideshow script on http://andrew.hedges.name/ , Safari throws a syntax error. Looking at the script, it's not apparent what the error is. Loading the page in Firefox 2 works and throws no errors.
Works for me with a local debug build of WebKit r24443 with Safari 3.0 (522.12) on Mac OS X 10.4.10 (8R218).
Andrew, have you tried a WebKit Nightly (http://nightly.webkit.org/) or the Safari 3.0 beta (http://apple.com/safari/)?
Sorry, guys. I checked this again and it was a case of Safari using a cached (and broken) version of the script.
