Hi there, wel this is my first time online with this new laptop and using
Microsoft Vista many things to download and install once online but basically
im trying to send pictures from my mobile phone to my computer using Network
Projector as i was told it works?? It's asked me to enter a network address
which i have entered http://server/projectors/projector1 Then a password
which im scratching my head about as it wont allow me to create a new
password. Can anybody help? Many thanks sam
