As I remember, the avatar photo is reduced in (file) size when it is assumed into the Profile -- and so can't be enlarged from the avatar that we see on the screen. Too bad, hey? I admit it might be an interesting way to raise funds for the site -- selling the secret code for enlarging - but not just now. Donations anyway are always welcome, though.
