How to add attachment in Yahoo Mobile Mail?

You can't it is not supported in yahoo or google mobile mail for bb. But you can start and save as a draft then do the attachment through a computer, laptop or ipad. After connecting your bb (bluetooth, wireless, or teathered) then add the image and send. Good Luck! P.S. removing your Simm from the phone does not seem to work either!
