So i didn't use artwork at all. Then i had an idea. I made some artworks my self to add them on specific genres i have on rekordbox. The purpose is to take advantage of the cdj screen and see some precious info of the track when i am on a playlist, without hiting "info". So the artwork i made look like this:



etc...
And on the cdj screen, on a playlist, they look like this:
nexus

nxs2

The colors are the same, i have for the specific genre on rekordbox.
Great!
So, why the hell can't i export this artworks on my usb drives? I connect a usb, it does sync, and nothing. No artwork on the usb...
I tried 2 ways to update the artworks, 1st directly from rekordbox, and 2nd from Mp3tag (by updating the artwork only and then hit reload tags on rekordbox). Nothing works. I get the artworks only when cdj's are connected via lan, not on usb.
When i change anything else (key,bpm,rating... anything), it get's updated on usb drives, by syncing. Only artworks don't.
I also tried varius dpi on the jpg's. The files are very small, 10-40kb. Any advice - solution?
