Thanks Dale. I've just tried it on my phone which is OS6. It's a bit clumsy.
Lets see if I followed what you were saying.
I just previewed it and it looks OK.
So the short answer to my original post is iOS 5 doesn't use image picker very often in the apps so upgrade to 6.
Which my iPad wont do of course.
Oh.... And Faterson, your link tip to the public folder will be my main option so thanks very much for that.
