No, you must use those in the BookyWay gallery. If there is not one of the images that fits your course / class, you can write to us at support.en@gymtrainer.net explaining your needs and perhaps attaching an example of an image you would like to have. We will look in our image bank for a photo that may fit your needs, and if you find it interesting, it will be inserted for free in the gallery, available to all BookyWay users.
