Your image is missing. However, based on your description here’s some options:
If the links to different articles are to articles on your site, you can create a Page Type for those articles that includes fields for the card’s image, description, and link title. Then you can create a slider widget that allows you to specify which articles you want to include in the slider. The widget might have properties for selecting the path or category of articles to display.
If the articles are not entirely on your site, you might create a content-only Page Type just for populating each card. Perhaps it would be a type named Slider Card. The next question would be where to put these Slider Card pages in the content tree. Take a look a Joel’s great article on Page Types. In short, you might create a special “Page Content” folder under each page for a place to organize child content used by your page.
