To upgrade from 14.04 to 15.04 you do not need the 15.04 image.  There
should be an option in the Software Updater to do it, or you can do,
in a terminal
sudo do-release-upgrade

Before you do that, however, can you describe the screen on which you
are asked for name/password and how you got to that page?
