Missing TV channel icons in Yatsez

Many thanks. This worked, as I am sure you know.
Reading the Kodi docs again, it does hint at this but does not explicitly say what you have to do! Why?
Anyway, onto next problem with my MCE remote which no longer does ToggleDPMS (custom command in keymaps.xml) since upgrade - the Yatse app (custom command) on my phone DOES still work…
