I tried file-thumbnail. But I couldn't display thumbnails.

{
	"$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
	"elmType": "img",
	"attributes": {
		"src": "@thumbnail.medium"
	},
	"style": {
		"display": "block",
		"margin": "0 auto",
		"max-height": "42px"
	}
}

Very sorry to hear that! A few additional questions for you:

• Are you still experiencing this issue?
• Are you part of targeted release (either as a user or a tenant)?
• Do you get any errors in the console when applying this format?
• If you change your format to the below do you see any errors within the rows themselves?

{
	"$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
	"elmType": "img",
       "debugMode": "true",
	"attributes": {
		"src": "@thumbnail.medium"
	},
	"style": {
		"display": "block",
		"margin": "0 auto",
		"max-height": "42px"
	}
}

@thechriskent .... I am also facing same issue, thumbnails are not displaying...is this feature not available for standard release yet?
Regarding your question "Are you part of targeted release (either as a user or a tenant)?"
I just changed Targeted release for everyone - how much time does it take to effect?

@thechriskent Thank you for the reply.

• Are you still experiencing this issue?

That is still continuing presently.

• Are you part of targeted release (either as a user or a tenant)?

No. Standard release.

• Do you get any errors in the console when applying this format?

There are no errors.

• If you change your format to the below do you see any errors within the rows themselves?

The following error messages are displayed on console.
“aria- Tag not found. Therefore, screen readers can not access the field.“

@tecchan1107 @thechriskent .....It started to work for me today ..I guess it is because I changed 'Targeted release for everyone' from 'andard release.' So mostly reason is that feature is yet being rolled out to tenants in phases....

@thechriskent When I also changed 'Targeted release for everyone' from 'Sandard release', I could display Thumnail.
Thank you!!
