To change pictures and links, right click on the picture and use Edit link or Image properties.
You can choose the size of the pictures yourself, but most common format is about 1200 pixels wide. A height of 300 or 400 is usually ok, but the main thing is that all the banners are the same size.
We recommend doubling the pixels in each direction (for instance 2400x600 for a 1200x300 banner) so that it looks better on 4K screens. Images are scaled automatically.
Some settings can be configured, such as having dots or number or boxes indicating which banner you are on in the loop, and the frequency. Contact us if you want to change anything.
