Question

"BannerImageUrl": {        
"Description": "https://[name].sharepoint.com/_layouts/15/getpreview.ashx?path=%2FSiteAssets%2FSitePages%2Fnrzh85no%2FNiceImage.jpg"",
"Url": "https://[name].sharepoint.com/_layouts/15/getpreview.ashx?path=%2FSiteAssets%2FSitePages%2Fnrzh85no%2FNiceImage.jpg"

Hello @FV

Thanks for reaching out!

To download the file uploaded in document library (referred as driveItem), use Drive Item Get Content Graph API.

GET /sites/{site-id}/drives/{drive-id}/root:/{path-relative-to-root}:/content  
GET /sites/{site-id}/drives/{drive-id}/items/{item-id}/content 

To download file/image uploaded to a list Item (referred as itemAttachment), currently Microsoft Graph doesn't have support for list item attachments, you can upvote feature requested submitted by other Graph users.

Add support for SharePoint List Item Attachments in Graph
