How do i assign artwork to a mix?! Cant seem to figure it out!!!

if you've already posted your mix,
go to edit
then

go to additional options
then under attach files: click on manage attachments
then under upload file from your computer: click choose file

Do you mean so it has like an album cover when you load the song up in a media player?

If so just use something like Itunes, right click the mix > Click "Get Info" > then go to the "Artwork" tab > then click "Add" and find the artwork you wana use
