I am on the iPad 2 right now on the iCAfe app. You click reply and it says Open Advanced Options. Unless it's different in the iPad 1 but I doubt that. It's the same app. Here are two pictures showing you.
I am on the the iPad 2 now on Safari on here. Yes, that's the reason why you can't do advanced options like photos. You can do them but you have to upload and post link. You should just download iCafe through the APP store. It's free and a very nice app.
OH and mods this should just be in the iPad section.
