does your phone have a data plan? if not it won't be able to send emails, unless otherwise supported by your wireless carrier
that said, you need to make sure that your phone can actually send to email, some cannot.
if it has bluetooth, that would be the best+ easiest way to get the pics off the phone onto a computer
another possibility if your phone has a memory card slot is to get a memory card that your phone supports and use it as a flash drive between 2 computers to transfer the pictures
