How can I show thumbnails and small images to guests while disabling attachments?

[ripley]

Here's the deal:

I want guests to see images.
I don't want gusts to be downloading the huge versions of the images.

So I enable "see thumbnails" and disable "download attachments."

Now my problem is guests can't see small images that haven't had thumbnails made.

Is there an easy fix for this?

Anybody?

I've never seen a mod to 'fix' this here.
