Possibly because of the way the site is coded using in the web page. Things like:
Code: Select all
<param name="movie" value="http://p.webshots.net/flash/simpleImageLoader.swf">
...
data="http://p.webshots.net/flash/simpleImageLoader.swf"
You can do something like blocking http://p.webshots.net/css/media.css, but then the layout is screwy.
