Actually, even if WebImageView still existed this method won't work,  
as the images are used without any plug-in interaction.

See <http://bugs.webkit.org/show_bug.cgi?id=10015> for more  
background.  The prevailing view is that all mime types are equal ...  
but some are more equal than others.  Quoting a comment in the bug:

I'm on record as accepting of, but not agreeing with, this argument ;)
