Thanks guys,
I did not explain the problem enough.
I want the character "@" to have it's background hidden. When you do that you
have to use alpha channel.
Note that most graphics on the below web-page are alpha channel but the "@" and one
of the "3"s is not.. and both of them look a bit tatty...
DONT FORGET TO HIT THE BACK BUTTON to come back here...
