A page from the _<I>thumbspage_</I> image-gallery builder 
used to create the gallery you're viewing.  

I coded this Python (plus HTML, CSS, and JavaScript) program
originally in 2016 because I needed it for my website; browser 
image views were too primitive and variable.  Since then, it's 
grown more sophisticated, with image scaling, slideshows, 
touch swipes, keypresses, and notes like this, but it has 
retained its basic static model for simplicity.  

See thumbspage's

and 2019's 
_<A HREF="2020 More Stew 1.jpg.html">update_</A>
for more info.  This also was an excuse to play with JavaScript, 
which is so much like Python that parts of it seem copied 
(because they probably were).
