If you choose to feature a logo, you can either include your YouTube avatar, or you can upload a custom image. For best results, the company suggests that you upload an image that is 800×800 pixels. You’ll also have control over which corner it appears in as well as when and how long the image appears on-screen.
It appears that this feature is still being rolled out, but you can check to see if you have access by visiting Settings > Channel Settings.
