Blocking all images except some

[Guest]

Can I have a script to block all images except the ones between, for eg.

<a href="http://mywebsite.com/img01-big.(jpg|png|gif)"><img src="img01-thumb.jpg" />
</a>

<<- The image which points to an enlarged version shouldn't be blocked. But an image like "<img src="banner.jpg" />" should be blocked.

How can I do it in Proxomitron or Proximodo?
