How can I add my own banner to donation page?

Your donation link can be found on the "Donation Settings" page.

If you can't find it, it's usually www.streamlabs.com/donate/YOURUSERNAME

The donation banner is the picture that shows up on your donation page.  The default is your twitch profile banner. 

If you would like to use something else, you have to find "Banner Override". 

Remember to use the direct link, ending in the file type.
