title: Add slider to home page of Laravel site
body: <p>Good afternoon everyone
  there is such a problem with the laravel website
  when I want to change the main photo of the site through the admin panel (I add new slides), they are not shown, more precisely there is a slider, but the added photos are not displayed
  Website - <a href="https://grandeconom.com/" rel="nofollow noreferrer">Used Home appliances</a></p>
  <p>After that, I tried to remove these pictures from the code, but they remained in the admin panel. I delete from the admin panel, they are not deleted, it gives an error (here is a link to errors)</p>
  <p><a href="https://drive.google.com/drive/folders/1s10bd5tyZ1Lt1Y2Z0tcBpLM_Y1Of8AyH" rel="nofollow noreferrer">https://drive.google.com/drive/folders/1s10bd5tyZ1Lt1Y2Z0tcBpLM_Y1Of8AyH</a></p>
  <p>I deleted these pictures only from the database. cheers it turned out !! )</p>
  <p>But I want to understand how to fix this error.
  or is there another way to add slides to the website
  I would be grateful if you can help
  Thank you in advance</p>
