Cover picture gets lost when saving to mp3

Maybe a beginner question…I try.

Using OS 10.7.4 and Audacity (from dmg), I want to modify mp3 music files.
The original files have/show already a cover picture,
when saving/exporting from Audacity, the cover picture gets lost,
i.e. the new mp3 file is with the original cover picture.

Is there a solution for this?
Do I do something wrong?
Do I miss a parameter setting?


Sorry, but Audacity discards lyrics and cover art. I’ll add your vote that it should not do this, though it is accepted as something we should fix.


Merci, bedankt, thanks, danke…

It seems to me that Audacity still discards lyrics and cover art of mp3 files?
Is there any plan to change this?
