  • Click on one of the "+"s inside the image to open the "Upload a Custom Background" window

4. Choose the image file

In the "Upload a Custom Background" window, click on the "Choose file" button to select the image you wish to use as your background. After the file has uploaded successfully, click "Upload background" to complete

Custom Background File Requirements

Custom Backgrounds must fulfill the following requirements in order to be uploaded successfully:

  • Must be a JPG or JPEG file
  • Must be bigger than 1,500x1,000 pixels

In order to get the right size, we recommend saving the image to your computer and then editing the size of the image in a photo editor before uploading.
