Add image to a song!

Hello, I want to add a picture to upload a song. According helpcenter the image should be 80pxX80px, but I’ve seen some authors who have bigger images.
I imagine you can get html inserting in the description of the song, I don’t know.
Someone can advise me?

Image banner need to be hosted somewhere.image

You need to upload an image anywhere on the Internet.
Copy adreed of this pic. and put it at this code

<img src="http://PICTURE ADRESS" />

Yes, it’s more correct for the description.

Great… thanks !!!
