If you manually take screenshots with *any* screen grabber and save in 
an appropriate format, this is apparently trivial -- use the ..image 
directive.  From the below, it appears that what you want is to have a 
literally up-to-date screenshot taken automatically during the doc build.

This requires that one be able to automate getting the application into 
the exact display state one wants to capture.  You can probably do that 
with a tkinter app if you write it with that possibility in mind.  In 
particular, you must keep a Python reference to every widget you want to 
manipulate, even if not needed for normal program operation.

There is also an issue with grabbing the whole screen versus only a 
program-specific window.

This (automatically) takes 'screenshots' on a no-screen (headless) *nix 
system (during doc build) by redirecting X-windows output to a 
pseudo-screen program.  Rather clever, and system-specific.

Or look into Windows screen grabber programs, of which there are many.
