Sorry for getting to this thread late - back from a quick holiday now.
I have written an image browser module that does what it sounds like
you're trying to do (and works with 3-D image stacks as well). It's
still quite rudimentary, and I hadn't really planned on sharing it in
its current state, but it may be that you can find some useful ideas
in the code. The image browser is a matplotlib canvas embedded in a wx
window, and I use the WxAgg backend - I've no idea how that will
change things from your setup. I run it interactively from ipython
-pylab as shown below.

Usage is pretty simple:

In [1]: import pyvis
In [2]: pv = pyvis.pyvis()
In [3]: pv.AddImg(arange(10000).reshape(100,100), 'my gradient')

then play around with the menus. More than one image can be loaded at
a time. I haven't had a close look at the memory usage, but it has
been working adequately for quite large image stacks
(1024x1024x250x8-bit). Feel free to use the code as you like.

Angus.
