Within SharePoint online, I would like to set a custom default image for my "thumbnail" column (or "Hyperlink or Picture"). I named it "Cover Photo". If I go into my settings for this specific column (displayed below), it invites me to put in JSON code. Is there where I can pull in a default image from a remote HTTP location? If so, how do I write that here in this JSON box area?

Normally, we could use following json to set default value for image column:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json" ,

  "elmType": "img",
  "style": {
  "width": "100px"
           },
  "attributes": {
  "src": "/sites/Team1/SiteAssets/__siteIcon__.jpg"
      }
}

Result:

Per my test, I use the image stored in current site, you can try to use images from remote HTTP locations.

  • That works when the SharePoint view is set to list. But does not work when the view is set to Gallery...regardless, I still like it.
