HELP PLEASE … posters being replaced by thumbnails

Forgive my english.
I am having this problem with kodi recently, when i try to update my local library it brings me thumbnails instead of posters like shown in this picture

i want posters showing like our friend Aladdin is doing in pic. shown above
………..
here is what i have done to fix it but never succeed,
– changing the scrapper
– reinstall kodi
– install Jarvis
– install krypton
– updated artwork downloader.
– i was planning on reformatting my computer anyway, so i installed both Jarvis and Krypton after reformatting my laptop, and still have the same problem.
am i missing something??

thanks in advance.
