Copy/pasted images in research not showing on corkboard

In the tutorial, there is an image in the research folder. This image page has an image icon in the binder, and when you open the research corkboard, the index card shows the image on it.

I copy/pasted an image from a wikipedia page into research. In the binder, the image has a normal text icon next to it, and in the corkboard, the index card is blank. When I open the document specifically. the image is displayed.

Is there a setting or other method for getting Scrivener to recognize the document as an image and display it on the corkboard?
