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.
