Not sure what "as each image is recorded" refers to, but if you want
to grab files via ftp, is there anything wrong with (in a separate
thread, I suppose):

import urllib2
urllib2.urlopen("ftp://ftp.example.com/pub/rhubarb.txt")

?

At a lower level, there's ftplib of course.

If you don't mind pulling in more code, no doubt Twisted could do this
just as simply too, and, I imagine, wouldn't need to use a separate
thread (never used it, but I know it has support for various common
GUI event loops).
