[Plugin: W3 Total Cache] CDN Rejected Files Filter Not Triggering

I have “wp-content/uploads/*” on my list of rejected files, but the plugin is still using my mirror for certain files.

excerpt from debug info:

/wp-content/uploads/2010/02/wolf1.jpg?w=150 => http://prstatic.appspot.com/wp-content/uploads/2010/02/wolf1.jpg?w=150

What’s even stranger is that it’s only doing this for the src= of the image, not the href=.

So the source looks like:

<a href="/wp-content/uploads/2010/02/wolf1.jpg"><img class=alignleft style="border: 1px solid white;" src="http://prstatic.appspot.com/wp-content/uploads/2010/02/wolf1.jpg?w=150" alt="" width="150" height="150" /></a>

Basically I want the src to remain unchanged, i.e. as /wp-content/uploads/2010/02/wolf1.jpg?w=150

It seems to me like the ?w=150 part is what’s messing it up. I’d replace them all myself, but there’s just too many of them on the site (the other authors don’t use html mode and I think wp just adds the ?w= part automatically, so it shows up in all their posts).

Any help would be much appreciated.
