Adding permanent image in SP online list

Question

So I am trying to create an ICT risk share list with SP online. The main requirement is adding the below image to the list for user information. So every time users create a new record, they can refer to this image to fill the form. With SP on-prem, we could add the new web part and use the content editor web part to add the image. I did some search, and I found the below code for adding a photo. However not sure how I can use "src" here to point to the image saved in the SP picture library.

can you please help.

{
"elmType": "img",
"style": {
"width": "100px"
},
"attributes": {
"src": "@currentField"
}

In SharePoint online modern experience, to show image on list form >> You have to configure the header section of list form using JSON formatting.

Use below JSON code in header section of list form:

{
  "elmType": "img",
  "style": {
    "width": "100%",
    "max-width": "100%"
  },
  "attributes": {
    "src": "https://<tenant>.sharepoint.com/sites/siteName/LibraryName/MyImage.png"
  }
}

In src attribute, pass the complete URL of your image stored in SharePoint library.

You can also use the @currentWeb token to dynamically refer the absolute URL of your current site like:

{
  "elmType": "img",
  "style": {
    "width": "100%",
    "max-width": "100%"
  },
  "attributes": {
    "src": "= @currentWeb + '/LibraryName/MyImage.png'"
  }
}

It looks like you're missing a final curly brace on the end.

By adding the curly brace, your JSON code worked fine for me:

{ "elmType": "img", "style": { "width": "100px" }, "attributes": { "src": "@currentField" }}

Once saved, SharePoint adjusted the JSON to this:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "img",
  "style": {
    "width": "100px"
  },
  "attributes": {
    "src": "@currentField"
  }
}

EDIT:

This is based on the assumption that it is applied to the "Picture" column in your list and the URL for "Picture" is pointing to the required image.

If you just want to use the same image every time, you can simply replace @currentField with the URL to the image and you can then leave the column metadata empty.
