So, TTW Python Scripts can be made unrestricted? Sounds dangerous.
(I like it :)

I took one of the images and started cutting it up in to smaller
parts. I cut it in half. No good. Then I cut the half in half.
That one got thumbnailed just fine.

So I am thinking it is one of two things:

= External Methods are restricted somehow in how much processing
  power they can use, or
= cStringIO uses a different method to move data around once
  the file gets past a certain size, and that is causing trouble.

I looked at the mailing lists, but I do not like getting so much
mail and don't like the web interface to the lists. I much prefer
to do this over usenet. (Works great for python, why not zope?)
