Have I understood correctly? - Drupal Slider\carousel modules
There are a lot of options within Drupal. This is it's great strength, but comes with a steep learning curve for starters.

So there are a lot of modules to build a slider. Most sliders require a content type where you upload the image and views to make the list of images. This is not to make it hard, but to give you options on what to do with it.

If you want an 'instant' slider, check out https://www.drupal.org/project/content_glider. No views required.
