How to copy single list attachment (as image) into the thumbnail/image column

Question

I have SharePoint records in a list that are dynamically created with Power Automate. Once the record is created in my SharePoint Online list, how can I say...

• Once the record is created, take the attachment value and copy it to the thumbnail column (Cover Photo) instantly so that the thumbnail has a visible image. (Is this possible today?)

Answer 1

Neither the new Image column or the Hyperlink or Picture column can be directly updated using flow.

A workaround is to use Send HTTP request to SharePoint action to update Hyperlink or Picture field.
