this might be useful for your 'in your ear' operations:
Code:

ffmpeg -loop 1 -framerate 1 -i massive.jpg -c:v libxvid -t 287 massive_loop.mkv
ffmpeg -i massive_loop.mkv -i massive.flac -c:v copy -c:a copy  massive_attack_final.mkv

then you need to consult this manual: https://trac.ffmpeg.org/wiki/Slideshow
--- i guess you need this but i did not try. give it a shot ;) ---

In this example the input images are sequentially named img001.png, img002.png, img003.png, etc.

Code:
ffmpeg -framerate 24 -i img%03d.png output.mp4

thanks for the pointer; works great

but poking around I found this script by Remko Tronçon
https://el-tramo.be/blog/ken-burns-ffmpeg/
which takes a bunch of photos and effortlessly turns them
into a "ken burns effect" type slideshow (with optional
audio).

It's quite something ... :)

the output did look incredible but the code messy and chaotic. anyway i do not need that. i go only for audio and people have only one static pic. my personal preference is to turn off video completely when listening to music.

I get that; but sometimes when "forcing" people to watch my
vacation photos, a little music and Burns effect might help ...

nobody should be ever forced to watch any vacation photos. my personal limit is 10 to 20.
