That's a good start. Follow the path to the channel icons the same way
the backend does (and fails currently).

The backend log will have an entry SIMILAR to this:

  Using configuration directory = /home/mythtv/.mythtv

That should reflect how the backend was started and possibly changed
is MYTHCONFDIR was set (MYTHCONFDIR overrides HOME).

See if the ChannelIcons Storage Group exists and if so where it
points. If it doesn't exist then the directory is automatically
set to ~mythtv/.mythtv/channels. Or some other user's path.

Keep testing using the Services API. When that works, the
rest will.

You can test from the command line and success looks like this:

$ curl <some backend>:6544/Guide/GetChannelIcon?ChanId=10201
Warning: Binary output can mess up your terminal. Use "--output -" to tell
Warning: curl to output it to your terminal anyway, or consider "--output
Warning: <FILE>" to save to a file

A failure (if the file can't be found) looks like this:

$ curl ofc0:6544/Guide/GetChannelIcon?ChanId=10209
<!DOCTYPE html><HTML><HEAD><TITLE>Error 404</TITLE><META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=ISO-8859-1"></HEAD><BODY><H1>404
Not Found.</H1></BODY></HTML

If you do: mythbackend --setverbose http you'll turn on additional backend
logging. But in the missing file case, it just tells you what you already
know:
