How do you add cover images to albums?
I use VLC on android for listening to music.
Today I wanted to add a cover to an album, looked it up and liked the idea of also having the CD-backing in my library so I downloaded both and named them "cover.jpg" (227 kB) and "back.jpg" (630 kB). Copied them over and VLC on my phone picked "back" as the cover for said album, so I deleted that file from my phone and the album went back to having no cover, even though "cover" was still there, the only image in the folder and smaller than "back"! Then I renamed the image from "cover" to "back" and it appeared as the cover! I also tried "folder" which didn't show up, went back to "back" and it showed up. Weird. Then I looked into other albums with cover art and many of them have no image in the folder at all. Can anyone explain how this all works? What am I not seeing here? Can it really be that vlc only accepts images named "back" as cover art?
