Are you sure? How would it know it was PNG (and not JPG or BMP)?
In any case, if there is a possibility that the caller might not want the
base64-encoded image to always be prefixed with "data:image/png;base64," then
passing it in is OK. Honestly, though, this is a test utility, so I don't image
it will ever get used.
