The author's comments a little confusing. He is saying that with iPhoto 4, APPLE has finally given user's the ability to choose Mail/Entourage/Eudora/AOL when sending photos.
The author then says this HIS PROGRAM will ADDITIONALLY send photos using the following email clients:
-Claris Emailer
-Mailsmith
-Outlook Express
-PowerMail
-QuickMail Pro
Too bad, netscape isn't supported. That is what my pops uses and he is too stubborn to try Mail, Eudora, or Entourage.....because netscape has mail integrated with the browser (UGH!)
