To clear up how J3 handles album art?

[mrapoc]

I have created this thread to ask for myself and others, how the hell do you get J3 to properly accept all album art?

I say this because I have tagged all mp3s on my computer using mediamonkey, all displays as it should whilst on the pc, yet on the J3 some will work, some will not, some will only work in matrix browsers and vice versa.

Is there a special way to add the tracks, a setting, some way we are breaking it?

Quite literally, everytime I try readding images/resyncing etc. I get a different result, always resulting in missing album art!
