Simple illustration

Yes. The runner converts JPG brightness into a heightmap relief and adds a base so the STL is printable.

Use invert when the raised parts are opposite of what you expect, such as white backgrounds with dark artwork.

PNG is usually cleaner for logos, but JPG works well for simple artwork and photo relief experiments.
