All she wants is the ability to highlights a set of photos and compress them and email them in one foul swoop.
Sounds like a Gmail account for email & Picasa on the pc for the photo sending would be the way forward. ( both free & Picasa sends via a Gmail account)
Picasa makes shrinking & emailing photos an absolute doddle.
Totally agree with Mikewsmith on moving away from ISP based email. - When you change your Internet provider - it's far far easier if you don't have to keep telling all your contacts your new contact details.
And whist your at it, I'd recommend more than one email address ....One for emailing family & friends, another for online shopping, forum signups etc.
