Pandora Music Streaming Tweak -- Change the Station Image

I've been a Pandora subscriber since 2006, and I have a couple of well-tweaked stations.  But one of my favorite stations was stuck with the ugly album art of the song that was used as the station seed.  I couldn't find a way to replace the image, and Pandora help had nothing to offer.  So here's how I changed the image:

1. Log in to Pandora.
2. Select the station from your collection.
3. Click the icon to edit the station. (At this time, it looks like a pencil.)
4. From here you can change the station Name, Description, and Thumb History, but most importantly, the "Seed" that the station evolved from, which is in the section called "Station Created From."
5. (If there are multiple "seeds" in this section you can skip this step.)  Click "+ Add Variety" to add a new "seed" and choose a favorite song whose album cover you prefer.
6. Delete the top-most "seed" to set the album cover from the next "seed" as the station image.
7. You can continue this process until the "seed" that has your favorite album art occupies the top spot.
8. At this point, you can add back the deleted "seeds" as described in step 5.  But for a mature station, you probably don't need to do this, especially if you've been diligent with the thumbs up button.
