Channel logo cache

Can you please add option to cache channel logos and poster images? Now on remote connection only virtual channels have logos. I have custom m3u with icons stored on home network. Same thing with program posters. I grab epg with webgrab++ and xteve caches it to my home network. The reason i cache epg is that i don't wan't to do unnecessary calls to epg provider and having my ip banned. And of course its faster also.

In addition to a channel logo and poster cache, we also need an option to resize these cache images files.
