Change thumbnail for sound

I couldn't change the image for sound. How can I replace it with another image? Also, the option given in Sound settings for the height has 'NO USE' as it doesn't work. I tried to resize the player, but only width can be changed but not height.

i hate the thumbnail for sound. pls anyone can help in how to change it?

Just add your files into : flash/modules/mp3/files

for example I will need setup my image for - 1.mp3, I will add 1.jpg file. That it's all!
If you will need that this procces will autimaticaly you'll need add field in upload form.

dhhh...i dont know how i missed that :) Thanks so much Sashae.
