I have a blank screen for my homepage - on purpose, I set it that way.
To email a picture in XP you just highlight(select) the picture then right click and choose 'send to' > 'mail receipient' and an email will open for you to write a message to go with it. Then when you open your email prog it is there in the outbox waiting to be sent the next time you are online.
Or you can just insert/attach the pic whilst you are composing an email.
Is he experiencing problems when he tries to do this?
What is it he wants to do?
