How do you add album artwork to your podcast?

First import the songs and add them to a playlist. Then you'll need to go online and copy the picture you want. (Ya know, right click and click copy.) Next go to your iTunes and get onto the playlist. Find the song in your playlist. There's a bar on the bottom left side of your screen with an up arrow I think. Click on it and there will be a "cut out" little thingy that says "Drag Album Artwork Here". Right click it and a little paste thingy will come up. If it doesn't, go back and recopy the picture.
