This will add a single slide in the admin interface, but this single slide will dynamically generate multiple slides in the published slider, based on the set parameters.
When you select this slide type the Content Type setting in the slide's Settings window will automatically be set to Content from posts . Also, in the Image editor, some fields will be automatically populated with data. For example, the [sp_image_src] will be added in the image's Source field and[sp_link_url] in the link's URL field.
[sp_image_src] and [sp_link_url] are dynamic tags and are used for fetching a specific data from the posts that were loaded. You can also use these tags in the Layers and HTML editors. Each of these editors have, in their inline info, a list of the dynamic tags that can be used inside that specific editor.
