Hi,

The string 'image_cache' doesn't exist in the mythweb source (or even
in the mythtv source.)

Could this be defined in a web server setting? Or, is it a link from
<someDirectory>/mythweb/data/tv_icons?

Try: locate -b '\tv_icons' and ls -ld on the response.

If the mythweb icon doesn't exist under tv_icons, then the Services
API is used to get it from the channels directory mentioned earlier.

WebFrontend does the same. Try: http://yourBackend:6544//Guide/GetChannelIcon?ChanId=someChannelID
It would be interesting if the same icons don't display in WebFrontend.
