This is typically done by screenshotting the mini icons you see when adding a card to Management (before you send it off; just the option screen). Alternatively, after finishing a lesson and seeing all the mini icons appear. But the first method has slightly bigger images than the second, I believe. Then the icon is rendered and cropped.
