How do I download album art?

[lordpuffer]

I'm running 10.13.6 on my iMac and I have VLC 3.0.11.1. All of my music, about 330 albums are on my computer and are all FLAC files. I would like to download the album art for each of my albums and have them embedded in my FLAC files. I tried to right-click on the VLC icon under Media Information, but it does not pull anything up. Can someone advise me on this? Thanks.
