Thumb for sound upload

How do you get the thumbnail to appear instead of the ugly dolphin default picture?

 i realize that but why doesn't the image associated with the upload appear? Is there no way to do this ?

I don't know if this thread will help but there is a discussion on that matter :

Sound Image

 looked at this thread this morning, seems like the tread is cut off, couldnt get it to work for 7.1.4 anyway. i did get songs to upload but still saw the default image.

Okay ill test it later in my site Ill update you.
