Album art not appearing on Android

[AisuClena]

Not sure where to put this, but hopefully this gets read, and I can find a solution.

I got Winamp on both my desktop, and my Android. On the desktop, all the album art is displayed correctly, it's all there, no mistakes. On my Android however, after I sync, not all the album art is there. Maybe about 75% of my albums that I've synced have album art. Is there any way I can make it so that all of them have the album art? It's really annoying.

Thanks in advance.

EDIT: Yes, I have tried the whole "Turn winamp off, connect to PC via USB, change Android folder to something else, then sync". It doesn't work, in fact, it made the % of albums with art lower.
