SMBW Level Thumbnails

[Crosstan81]

Does anyone know how to get the thumbnails for the levels in Super Mario Bros. Wonder? I know you can take a screenshot of it but that has text on top of it and everything. I just want to get the plain images.

I'm not sure if this is what you're looking for, but it looks like The Spriters Resource has them.
