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.
