Primefaces graphic image
http://www.primefaces.org/showcase/ui/dynamicImage.jsf is supposed to be
able to load the image from the database, but I can't guarantee because I
haven't used it. Back when I was doing JSF (been a while now) I hijacked
the h:graphicImage tag so that it would perform as usual, or load form the
database depending on the library. I wrote a blog post about it:

If the primefaces component will work for you it's definitely easier than
the way I did it. As for upload, I echo what Jason said.
