Here's a finaliser that runs:
class Spam(object):
def __new__(cls):
instance = object.__new__(cls)
print("instance created successfully")
return instance
def __del__(self):
print("deleting", repr(self))
An example:
py> s = Spam(); del s

I don't even understand this. What does it mean to sort images visually?
Which comes first, a 400x500 image of a cat climbing a tree, or a 300x600
image of a toddler playing with a dog?

I need to sort images (*.jpg), visually, not by file name.
It looks, there is no standard UNIX tool for this job?
So, I have to write one by myself, using Tkinter.
Are there any high-level widgets which can help me, for example a file
browser with thumbnails?
