My first Google search for
"tkpng" "python"
gave no usable results. So I am not sure if and how can I use these Tk 
extensions from Python...
And finally I want to show the picture(s) on a Tk-based Canvas on top of 
each other with properly handled semi-transparency.

In our project we want to use as little as possible additonal packages 
because we expect that the end-users will use several platforms (Windows, 
Mac, Linux) and installing any extra Python-related package on non-Windows 
platform seems to be a nightmare, at least that is the result of the past 
three months of experience.
The need to go to the command line level for such a basic thing like 
installing or uninstalling something seems to me like going 20 to 30 years 
back in history. We cannot expect that our end-users (especially the 
Mac-based ones) will have that expertise even if they have enough expertise 
to program in Python when it is finally correctly installed on their 
computers.

I was actually negatively surprised by the lack of this very basic feature 
(especially in a vector-graphics-based environment) when I started with 
Python+Tk a few months ago, so I was very glad to see it in 8.6 and I 
immediately started using it on Windows. But then I receved complaints from 
a Mac user that it just does not work...
