I have commented previously that I have to upload one pic, and 'insert' it, before I start the next, and limit to three pics. If I then 'send' it, then 'edit' I can add three more, and so on.
As Sarah said, copy your text before you 'send' it, then if it goes toes-up, you haven;t lost all the work.
if you are calm and collected when all about you are going berserk - you've missed something important!
