Very likely :-), but not immediately. I'm working on a couple other bits 
of code at the moment.

Your/xterm's use of XReparentWindow() was not used in the coding 
approach taken by feh(1). Better, it's simpler than what I'd planned to 
try in my next attempt in creating the preview window completely under 
the passed id, where one passed.

(1) - FWIW. I slipped up and didn't say it when I posted the 
f_distribution() sample images, but those were done with feh's caption 
highlight method. You'd been discussion highlight options/colors for 
your table include...

I use 'xv' and (the window manager's own) 'wmiv' as image viewers, but had a
quick look at 'feh's man page, and would be interested how its '-list' output
compares to '$ identify *'.

re "coding approach", perhaps look at 'xterm' (or some other "old" utility)
source instead.  also, ought to have mentioned that the actual call to
XReparentWindow() is conditional on a call to a wrapper function
('xtermGetWinAttrs()') succeeding; that, essentially, is a
'XGetWindowAttributes()' call to see whether the id is valid.

I think they should be called labels not captions, as they're inside the images
:-).  natty dash separators, are they supplied or did you have to type them?

'identify hmm.png'

'feh --list hmm.png'

Both generate a lot of noise if you ask them to read files / formats 
they cannot.

Labels/captions. I leaned on feh's thumbnails and - caption directory 
text files for each image - feature. These are sometimes actual captions 
and sometimes more like labels depending on - a lot of things. FWIW... :-)

The dashes I added on the fly while editing the caption files. The 
caption files can be paragraphs of text or what ever you want to put in 
them. Positioning is limited to lower left corner or lower centered when 
over an image and pretty sure something similar for actual 
index/thumbnail captions.

---
Wild aside on feh:

I moved to feh as my 'quick' image viewer because it can use a large 
cache and so not bang on my actual disk drive while displaying and 
visually comparing images. The latter I do a lot - a quick switch 
between two images to see what my eyes pick up. I could never get 
programs like eog not to not use my actual disk drive without a fair bit 
of extra set up/work.

Anyhow, feh has some interesting features like being able to create on 
the fly hot index/thumbnail images. Further, you can code up a number of 
actions on key sequences while an image is displayed.

Not explored it too much yet, but this looks a fair bit of the framework 
needed to create additional automation around my full scene test cases.

Or, perhaps to back a collection of images with help text / actual scene 
files / rendering changed files on the fly / ...  At this point just a 
possible path to such things I guess, but looks interesting.

thank you v much.  I may yet install this, to try out, quite like the tiled
view, and am intrigued by the (snipped) mention of keyboard macros executing.

and per directory caption files too sounds an interesting feature, know of no
equivalent.

now thinking of adding dashes to Tabulated()'s caption.  :-)

the 'frm.tk' script has the drawback that it exits when the client's window is
closed (ok for terminal, not so for this use).  attached a version which uses a
different "pattern", providing as many frames as needed, one at a time; the
frame's dimensions too are now easily adapted.
