How set copy/clipboard format back to Image/PNG ?

I am a noobie who only started using HeidiSQL (11.3, Windows 10) properly yesterday Initially, when I copied a Query result, the clipboard contained a PNG image (useful to paste into a simple document) Since then I have fiddled with various copy/export formats (eg JSON)

Problem: Now I want to set it back to copy as PNG image, but don't know how. Image/PNG does not seem to be listed as one of the options.

Please, how do I restore this useful option?
