The w3mimg protocol is documented in the source files like this:
0 1 2 ....
+--+--+--+--+ ...... +--+--+
|op|; |args |\n|
+--+--+--+--+ .......+--+--+
args is separeted by ';'
op args
0; params draw image
1; params redraw image
2; -none- terminate drawing
3; -none- sync drawing
4; -none- nop, sync communication
response '\n'
5; path get size of image,
response "<width> <height>\n"
6; params(6) clear image
params
<n>;<x>;<y>;<w>;<h>;<sx>;<sy>;<sw>;<sh>;<path>
params(6)
<x>;<y>;<w>;<h>

Yes, reads from stdin, writes to stdout. You might also just execute
w3mimgdisplay and type your commands there. Check the source for command
line parameters it accepts.

Start by strace'ing w3m?
