Are you sure? Is the artwork displayed by other apps?
Do you have a tag editor program to confirm your suspicion?

iTunes, I believe, can hold artwork separate from the audio files, I.e. in its own 'database'. This is unavailable to other servers such as MinimServer and Asset.

A solution to this can be found in this old post.
There may be other solutions.
