### One-sentence description Event specific banner/slides. ### Motivation It is awesome and the standaard images get boring ### Desired functionality For an event it should be possible to add a slide, just as now possible for the front page. If the slide is added for an event, it might also be nice to automatically show it on the front page ### Suggested implementation Something like documents per event, but for slides I guess. I honestly have no idea how much work it is but it seems nice
