Thank you for your suggestion which I have just tried with inyteresting results. It is something to do with a fault when I send, which is very odd. If I send it to myself it is blurred, and when I receive it, it is blurred. If however, I receive on another computer it is okay, and if I then forward to the original computer it is okay! So, I guess it should be okay to send to friends or brides etc, even though it looks blurred, it should hopefully be received okay.

(I know about the normal jpeg attachments, but Adobe has its own method of sending a load of pictures in a normal email, which look great but uses very little memory, unlike an attachment).
