Most album artwork gone

[bamit11]

So I was trying to clear up space on my Android phone, and I accidentally deleted a file that looked like it held the album artwork for Spotify, and after doing this, most of the album artwork on my phone is gone. It doesn't seem to matter whether they were local files or not, just most of the covers are gone. I would like to solve this without having to redownload Spotify because if I do I will most likely lose all of my local files from my phone for a month or two.
