You can edit the used teaser images in the Template Builder at any time.
To select a teaser image, click on the “image” icon in the middle (the icons appear when you move the mouse over the teaser image).
A pop-up window opens.
You can select images that are already available by ticking the box or upload a new image.
Don't forget to save your changes!
You can change the aspect ratio of the image using the "settings wheel".
