No Artwork from USB Hard disk.

I hope someone can help me.
I connected a USB HD to the USB port of my Wiim Ultra, where all my music album collections are located. Only in a few cases are the related artworks visible. I noticed that the files of the visible ones were named folder.jpg.
I tried to rename some others, for example, from front.jpg to folder.jpg, but they remain invisible. I also tried to scan the USB disk but without success. How can I solve it?

Delete the WiiM cache folder from the usb drive and redo the scan

Edit: delete the WiiM app cache too if you can, or delete and re-install the app to clear it

I confirm that this is how it works! Thank you.
I'm also wondering if there is a way to view more than one artwork for each album. For example front cover, back, inlay etc.
