For your posts related to the role-plays we want you to choose a featured image (see also How to… add a blog post) of the following style: 
Under Media you will already find a selection of possible images of the roles of the past year. However, not all roles already have an image for use. In this case you have to open pictures_roles and create an image yourself. Insert the name of your role into one of the slides, cut the image, e.g. with the Snipping Tool, save it and upload it to Media.
To upload an image, click Media and Add New.
If you run into any problems, please contact the course coordination.
