"SVG as image" is basically SVG with scripting disabled and no event  
interaction. Ideally "declarative" animations still run as long as they  
don't depend on events. I believe in Opera they currently run for <img>,  
but not for 'background-image'.

I only said that scripts were disabled... Anyway, as for being  
non-interactive, it is true that if the <img> has ismap= or usemap=  
specified things are slightly different.

Non-interactive in the context of HTML 5 is as far as the Web page is  
concerned. <blockquote> is also non-interactive yet the user agent could  
offer a way to get to the citation URI.
