Why didn't I see the Preview Image when I dragged it out of a node

as title,Can you tell me how to add it? It's too troublesome to always search for a Preview Image node

Try setting a higher number of suggested entries on there from the settings menu, the suggestions just pick the first things they find in no particular order that'll accept that output type and it's probably dropped just off the bottom thanks to the custom nodes. I have mine set to 10 instead of 5.
