- You can read about artwork requirements over at Blubrry. Here are the highlights:
- 1400 x 1400 pixels and a maximum size of 3000 x 3000 pixels
- .JPG or .PNG, whichever is smaller, probably .JPG
- Looks good at 60 x 60 pixels
- RGB color
- Inkscape is a free art program that I used to make the artwork for my podcast.
