To upload a logo, select the Logos & Branding tab from the top right menu:
Upload your custom logo here. This will be used in place of the business name and the profile icon on your homepage and email invites. We recommend uploading a .png file with transparent background.
Gallery Cover Logo:
This logo will only appear on the cover photo of your galleries. Since this logo image will be applied directly on top of an image, a white/light version of your logo is recommend.
You can use the built-in auto-generate tool to create a white version logo from the Logo Image you have uploaded.
