Hello,

first of all I have no knowledge of pygtk. But after some googling I
have found something that might help you:
http://trac.bjourne.webfactional.com/ GtkImageViewer. It also comes
with Python bindings.

For the crop functionality, check the docs:
http://trac.bjourne.webfactional.com/chrome/common/pygtkimageview-docs/
, there is a function ImageToolSelector
(http://trac.bjourne.webfactional.com/chrome/common/pygtkimageview-docs/gtkimageview.ImageToolSelector-class.html)
that can be customized to make an image cropper.

Well, I hope my little finding can help.
