The main slide is a 2000x400 pixel image located just below the header of the web portal which illustrates with generic or detailed images the most relevant aspects of each degree. The component that contains the slides reproduces them in the form of a carousel and you can put as many as you want, although it is recommended not to exceed five or six. They can also be used to announce specific events, can incorporate a title (like the one in the attached image) and can be linked to an internal page or an external website. The playback order is random and cannot be varied. 
The slideshow component is placed in all the web portals, and you only have to drag the slides you want to publish into it.
To generate a slide, create a new element 'Front page spot', and fill in the corresponding fields, with the option to add title, description and link. If the slide has a title, it will have to be translated into the three languages. Once generated, from the 'My work' section located at the bottom-left of the web manager, we will drag it inside the component. 
We must not confuse the main or homepage slide with that of the inner pages. For an inner slide we will generate the element ‘Inner spot', and the image that corresponds to it must have dimensions of 1180x200 pixels. To publish it, you do not have to drag it to any component, but to the 'Inner page spot' field of the page or pages where you want it to be published.
