It remove every cover art of a song it played, resulting blank cover art in iTunes. I have never seen a software suck like this.

Hey Yanglifu90, Welcome to the Nokia Forums!

If album art is missing in Nokia Ovi Player, it can be added on your PC manually in either of the following ways:
1) To add an image that is stored on your PC, right click on the album in your music library in Nokia Ovi Player and select Edit album details > Album artwork > Add picture.
2) To update album art through Ovi Music service, right click the track or album name in Nokia Ovi Player and select Get album artwork.

To attach album art on your mobile device, browse for the album or track in the mobile device music player, and select Options > Album art > Options > Change. This option is not available on all mobile devices.
If album art is missing in your mobile device and if there is no option to add/change it with music player, please, check that album art is available in Ovi Player. Then delete track from phone and import from Ovi Player again. Now the mobile device should display album art. If the album art still does not show on the device, try step 1 (adding the art manually from PC).

I hope this helps and please get back to me if you are still experiencing the problem!
