[Mr. V]

I follow your hint, especialy Mr. Vs hintz to read the new folder rules. FInaly it seems to be no difference at all, the new structure can be used but must not used. So I edit my advancedsettings.xml to enable all artwork but I see only clearlogo there, not logo. FInaly I rename one logo.png to clearlogo.png and it appears imediatly
Now the question is, must I rename all my logo.png to clearlogo.png or can I edit a settings file to fix that behaviour?

Thanks in advance for any hint

I used a bulk rename program, search for all logo.png and rename to clearlogo, done in 5 mins , over 2000 films, Did the same for music and cdart.png files to discart.png

Ok, I guess I will do it the same way but I see that Kodi use logo.png and clearlogo.png in different ways. Thats why I ask if there ae maybe other options as well!?

@olarf
Renaming you files will be the best way to fix logo's ect not showing. I also used bulk rename utility in the past when I had to rename my files. Some time back there was a thread talking about having a standard naming scheme for extra artwork that is reflected in the kodi wiki. The skin is coded to use the recommended file names. So, for the best compatibility for this and other skins you will need to rename your files.

For the naming of files kodi uses clearlogo.png and clearart.png. 'logo.png' is not used for the recommended filename.
