[Pythoncard-users] pass a component a StringIO.. possible?

I'm trying to avoid saving a jpeg to a temp file before loading it into a
Pythoncard gui component. Something like:

import Image

filename = "whatever.jpg"
im = Image.open(filename)
im2 = im.resize( [512, 384] )

self.viewerWindow.components.pic1.file = im2

The above errors out of course, because the component is expecting a
filename. I'm wondering if anyone knows how to do this without having to
save im2 to a temp file? I gather StringIO can do this, but I can't figure
out how.

Thanks for any help.
