This is quick and easy, so jump right in and click on the Logos button.
Clicking on the Logos button, you will be given a screen for a logo upload or choice of a logo you've uploaded previously.
If you’ve already uploaded a logo image in the past, just click on the Library button to see your images. If not, use the Upload button. Be sure to size the image to 259 x 100 pixels. Next you’ll upload a Favicon if you want one.

Upload your image in a 32 x 32 pixel size and the .ico or .png image types.
