I'm not using a front-end, but I put my channel images in:

# ls -la /var/lib/mythtv/.mythtv/channels/
total 116
drwxr-xr-x 2 mythtv mythtv 4096 Jun 17 14:33 .
drwxr-xr-x 8 mythtv mythtv 4096 Jun 25 15:40 ..

by hand.  These are then copied into:

after accessing MythWeb.

I have a /var/cache/mythweb/image_cache/ directory, but it's empty.

I'm using the Debian packaged 0.28.2-dmo1+deb9u1 from deb-multimedia.
