A while after posting this I actually figured out myself.
A .jpeg with "cover" or "folder" as name does indeed work (didn't test more alternatives). Xion auto-fetches the image and applies it just fine .
flac uses its own native tagging system, so I thought Xion just couldn't display, but it seems I was trying to add the album art incorrectly (More specifically through an ID3 editor. Even though the other info works if added through that, album art seems to be the only one that doesn't get fetched correctly if added that way).
After trying this out, however, what method is Xion using to scale down the album art?
Is it using nearest-neighbor interpolation? If so, would there be any chance of switching it to bilinear or bicubic (or applying anti-aliasing)?
I'm using images usually with about 500x500. When it scales them down (to roughly 110x110, in my case), it introduces....scaling aliasing (I believe that's it)? The result is something like this:

Thank you for the replies, either way, both of you.
And good luck with getting your life in track, Cliff. Been using Xion for years and hope to keep it that way!
