How to set a background image on a Space?
When you create a new Space, mouse over to the right side of the page where it says “Name this Space.” You’ll see an image of a mountain where you can click to upload a file and set the mood of the Space.
Once the image is selected, click on the Save button and the image will appear in the background.
In order to remove the image that is set on a Space, simply click the "x" button and the image will be removed.
(Please note that 600 x 450 is minimum background image size)
