While you’re live streaming using the free version of Yostream, you can access all of the essential features that add a dash of magic to your live stream. But, given the limitations, you can’t weave your personal touch into every pixel. This applies to the logo as well.

Of the four icons, located linearly at the bottom-right corner, click the third - Brand.
Select Graphics.
Click the '+' sign to add your custom logo.
If you're using the Free plan, you'll be asked to upgrade it as uploading custom logos is allowed only under premium pricing plans.
