Not a regression from Safari 2.0.4 on Mac OS X 10.4.11 as it has the same issue (perhaps even worse).

What happens is that the web server occasionally returns an error page that says it's forbidden to view the image.  This happens frequently with Safari 2.0.x and 3.x, but never with Firefox 2.0.0.x.

You may verify this by doing the following:

1. Launch Safari/WebKit.
2. Log into Yahoo! Mail Classic.
3. View a mail message with more than 1 attached image.
4. [OPTIONAL] Reload the page until some image thumbnails fail to appear.
5. Right-click on a missing thumbnail image (or loaded thumbnail image) of the message, then select the "View Image in New Window" option.  (NOTE: This seems to reproduce better with the second thumbnail and beyond.)
6. Hit "Reload" (Cmd-R or Reload button) until a "Sorry, forbidden." HTML page appears instead of the image.

A wireshark (tcpdump) of the HTTP headers sent in the working and failing cases shows them to be identical.

I can't reproduce this anymore on Yahoo! Mail.  Closing.
