To change your banner photo, you will need to first go to your profile page. This can be accessed by clicking the profile icon at the top-left of the site, next to the Sigma Home button or by going to sig.ma while logged in.
Once you’re in your profile, you can click the camera button on the banner photo.
Click the ‘Choose New File’ button at the bottom of the pop-up window and select the file you want to use. A recommended image size for the banner size is 1440px x 180px.
When the photo is uploaded, you can move it and resize it as you like.
Click the green “Save” button at the top-right of the page once you are done positioning your photo and your new banner photo will be saved.
