You need an URI for your image. Either your server generates a "Data URI"
(https://en.wikipedia.org/wiki/Data_URI_scheme) or you write an
ImageServlet that can serve your image's byte array with the correct HTTP
content type so that the browser can render the image.
So in case of data uri you would have something like
new Image("data:image/png;base64,<your image bytes as base64>")
and in case of an ImageServlet it would be
new Image("/images/<identifier>.png")
where <identifier> is used by your ImageServlet to load the image from the
DB, maybe convert it to "png" and then send it to the browser using
"image/png" as response content type.
