Looks like the fragment case was missed in https://bugs.webkit.org/show_bug.cgi?id=69211.

Empty URL is a special case in HTML5. We'll need new research for src="#", and a change in the spec if it's warranted. See <http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-December/024357.html> for a discussion that resulted in changing the spec for empty URLs.
What do other browsers do?
Vsevolod Vlasov
I used following test cases:
1. <img src=""></img>
2. <img src="#"></img>
3. <img src="#test"></img>
Opera 11 makes only one request (main document) in each case, so they are ignoring fragment and consider "#" an empty url.
Firefox 3.6 makes one request in the first case and two in other cases.
Firefox 8 makes two requests in each case (so they are making two requests for src="" again!)
Chromium/Safari with ToT webkit make one request in the first case and two in other cases as we would expect.

Please file a bugzilla.mozilla.org bug for them to fix.

Getting a spec change first is probably the best way to go about this. Would you be willing to e-mail WHATWG?

How common is this? Unless it's really common (why would it be?) I'd suggest not doing anything special for the latter two cases. (src="" is common because it's the default value.)
